+## Running LaGriT
+
+LaGriT consists of mesh **commands** and options that are used to create, modify, optimize, and write files. LaGriT can be run on the command line interactively, so commands are entered one at a time at the prompt, or with one or more files containing the LaGriT commands. By convention we use ".lgi" for lagrit input file names and ".mlgi" for macro files called from main command file.
+
+Run LaGriT from the command line interactively or put commands in a file and redirect.
+```
+lagrit
+```
+or
+```
+lagrit < input.lgi
+```
+**Important Note:** the **`finish`** command must be used to exit interactive session and must be at end of command file.
+
+## LaGriT Syntax Conventions
+
+LaGriT reads commands and command options from each line at prompt or each line in a file. Each line starts with a **command** followed by command options. Syntax is very important and the [commands](https://lanl.github.io/LaGriT/pages/commands.html) reference pages should be followed, or errors may occur. The following conventions apply:
+
+- Lines are a maximum of 80 characters long, identifiers and file names are a maximum of 32 characters long.
+- A line can be continued by an “&” as the last character of a line to be wrapped.
+- Command and token separators are comma, slash, or blank. (‘,’ ‘/’ ‘ ‘).
+- White space is ignored except between slashes with empty space indicating default for that option should be used.
+- LaGriT will ignore lines that start with comment indicators '*' or '#'.
+See more at [Syntax Conventions](https://lanl.github.io/LaGriT/pages/docs/conventions.html)
+
+## General Meshing Definitions
+
+- **Mesh = Grid** = elements defining geometric shapes allowing numerical computations for simulations 
+- **Node = Vertex** = point = mesh object nodes that can be used to connect into elements.
+- **Element = cell** = nodes are connected into element types such as line, triangle, or tetrahedral (see page)
+- **Structured mesh** = a mesh whose connectivity (topology) can be defined implicitly, and cell neighbors are predictable. Generally, a quadrilateral mesh in 2D and hexahedral mesh in 3D. 
+- **Unstructured mesh** = a mesh that requires explicit connectivity information to describe cell topology. Generally used to represent complex shapes. 
+- **Delaunay Triangulation** = a Delaunay mesh (triangles in 2D, tetrahedra in 3D) has cells such that the circumcircle(2D)/circumsphere(3D) contains no vertices other than the cell vertices. A Delaunay triangulation maximizes the minimum interior angle. 
+- **Voronoi Tessellation** = the dual of a Delaunay triangulation, meaning that the vertices of one correspond to the cells of the other, and the edges of one correspond to the edges of the other.
+    - Defined as ```V(pi) = {x | d(x, pi) ≤ d(x, pj) for all pj ∈ S, j ≠ i}```  
+    - The Voronoi cell V(pi) contains all points x that are "closest" to the site pi.
+    - "Closeness" is determined by the distance function d(x, p).
+    - The inequality d(x, pi) ≤ d(x, pj) ensures that x is closer to pi than to any other site pj.
+- **Control volume (CV) method** = in context of computational hydrology, the discretization method used by physics codes such as FEHM and PFLOTRAN for solving multiphase flow of fluid and energy (heat) in porous media. The CV method guarantees conservation of mass and heat.
+
+
+## LaGriT Meshing Definitions
+
+- **Current Mesh Object = mo** = is the mesh data structure used in LaGriT. 
+- **imt** = integer material type = default name for vertex array with positive integer values indicating material ID or color.
+- **itetclr** = integer tet color = default name for cell array with positive integer values indicating material ID or color (legacy name convention)
+- **itp** = integer type = vertex integer tag indicating type such as interior, exterior, interior boundary, or exterior boundary. 
+- **geometry** = is created with surface and region commands and is used to set mesh material values. 
+- **LaGriT (.lgi and .mlgi)** = LaGriT command files suffix where .mlgi is a macro called from main command files. (Optional suffix convention) 
+- **AVS (.inp)** = Advanced Visual Systems ascii file format for mesh information (vertex coordinates, cell connectivity, vertex attributes, cell attributes) recognized by most VIS applications. LaGriT can read and write AVS files. 
+- **Exodus II (.exo)** = Binary mesh file format built on NetCDF data storage structures used for Amanzi/ATS and recognized by most VIS applications. LaGriT can write Exodus II files but does not read Exodus II files. 
+
+
+## LaGriT Basics Tutorial 
+
+
+This tutorial shows how to use LaGriT commands to create a simple structured multi-material mesh and files for simulations. This workflow starts with a hexahedral mesh which is connected into a Delaunay tetrahedral mesh. Materials are assigned to the cells and vertices using surfaces. The final step writes files used for simulations such as FEHM. 
+
+You do not need to run LaGriT as the example output files are included in this tutorial. But new users will benefit from running the examples and making modifications to better understand results of different commands and their options.  Paraview is used to create the images in this tutorial and can read any of the AVS *.inp files. 
+
+
+## [Step 1. Create a Hex Mesh](step_01.md)
+
+## [Step 2. Convert Hex Mesh to Tet Mesh](step_02.md)
+
+## [Step 3. Assign materials to the Mesh](step_03.md)
+
+## [Step 4. Write Mesh and FEHM Setup Files](step_04.md) 
+
+
+## Final Word
+
+
+Meshing with LaGriT is not automatic and methods can be complex. But LaGriT tools provide a robust variety of meshing tools with capabilities specific to geologic applications and Voronoi control volume solvers. For some modeling applications, the LaGriT workflow can be generalized and easier to use. Applications using LaGriT for meshing include dfnWorks and Tinerator, both on GitHub and available for download. We hope this Tutorial provides insight into LaGriT and how it may solve your meshing needs.

+
+
+## Create a Mesh Object
+
+
+A mesh object can be created by reading a mesh, ie ```read/avs/mesh.inp/ 3dmesh```
+or the mesh can be created. For this example, we will start with one of the [`createpts`](../../docs/commands/createpts.md) commands. These are used to add points to a mesh object with defined distributions.
+
+For your first command you will create a 3D mesh object and name it `3dmesh`. This will be a structured hex mesh, so we add the element type to the end of the command syntax.
+
+See more on the Mesh Object data structure at [LaGriT Mesh Object](https://lanl.github.io/LaGriT/pages/docs/meshobject.html)
+
+*Note on spacing: the slashes separate keywords. The slashes with empty spaces are place holders if the user wants to define npoints or nelements in the command. We do not define these here since these values will be updated in the mesh object as points are created.*
+
+```
+cmo / create / 3dmesh / / / hex
+```
+
+View the contents of this empty mesh object. Note the mesh attributes nnodes and nelements is currently 0. LaGriT book-keeping routines will update the mesh object as it is modified.
+ 
+```
+cmo/status/3dmesh
+```
+
+*Note: the command **cmo/select/3dmesh** can be added here, but not necessary because there is only one mesh. Also, the **create** command makes the created mesh the current mesh.*
+
+
+## Create Points for Hex Mesh
+
+We will use one of the simple **`createpts`** commands, this version will create a structured rectangular mesh. Checking the syntax for [createpts/brick/](https://lanl.github.io/LaGriT/pages/docs/commands/createpts/CRTPTBRICK.html) we see options that can be defined as variables, making them easy to change.
+
+In LaGriT, variables are assigned using the `define` keyword. We define the variables before the commands. It is good practice to locate these all together with comments at the top of the command file. You can also use the **define** command multiple times, the last will overwrite previous values. This is an easy way to keep track of resolutions as you try them.
+
+```
+# Mesh domain 100x50x80
+define / XMIN / 0.
+define / XMAX / 100.
+define / YMIN / 0.
+define / YMAX / 50.
+define / ZMIN / 0.
+define / ZMAX / 80.
+
+# Set the number of points along each axis
+# Spacing of 10 will have 11 points for length 100
+define / NX / 11
+define / NY / 6
+
+# try 10 meter spacing with 9 nodes first
+# overwrite and use 5 meter spacing with 17 nodes
+define / NZ / 9
+define / NZ / 17
+```
+
+Above, the spatial domain (MIN and MAX values) and node density (`NX/NY/NZ`) have been defined.
+Now we can use the define values to add points to the mesh object.
+The [`createpts / brick`](../../docs/commands/createpts/CRTPTBRICK.md) command will generate a defined number of
+hex elements across a defined domain. 
+
+`NX` number of hex elements, along with their corresponding vertices, will be created in the spatial domain along the X axis, with `NY` elements in the Y domain and `NZ` elements in the Z domain.
+
+```
+createpts/brick/xyz/ NX NY NZ / XMIN YMIN ZMIN/ XMAX YMAX ZMAX / 1,1,1
+```
+
+As shown in the screen report, **`createpts/brick`** creates 1122 hex points and 800 hex elements. The connect option should not be used for the **brick** option because the hex connectivity is created automatically.
+
+
+## Set Materials and Boundary Tags
+
+
+It is good practice to set materials for nodes (imt) and elements (itetlcr) to 1 before continuing. A 0 value in these arrays will cause some viewers to ignore that point or element. These attributes must be positive non-zero integers.
+
+*Note 1,0,0 represents all for node start,stride,end*
+
+```
+cmo / setatt / 3dmesh / imt / 1,0,0 / 1
+cmo / setatt / 3dmesh / itetclr / 1,0,0 / 1
+```
+
+It is also good practice to reset the itp attribute anytime materials are changed. This attribute indicates which nodes are on the boundary and which are internal and is used in many of the meshing routines.
+
+```
+resetpts/itp
+```
+
+## Check the Mesh
+
+
+View the Mesh Object status, brief version. This report affirms the creation of a 3D hex mesh. The **brief** option shows the cmo header without all the attributes.
+```
+cmo/status/ 3dmesh / brief
+```
+
+View the min max values of the mesh attributes of the coordinates as another check.
+The keyword -all- or -xyz- can be used to view mesh object attributes.
+```
+cmo/printatt/3dmesh/ -xyz- minmax
+```
+
+Check the mesh with the **`quality`** command.  There should be no negative or zero volumes.
+
+```
+quality
+```
+
+## Write the Mesh and View
+
+
+Write an AVS format mesh file for viewing the mesh.
+This file can be rendered in certain scientific 3D visualization applications such as Paraview.
+
+Viewing this mesh, you should see something like the image at the top of the page.
+By default, Paraview will color the mesh by imt values which are all equal to 1. 
+
+View the mesh using the node attribute itp to see the boundary nodes. The outside nodes will have value of 10 and internal nodes will have value 0. Note when viewing a mesh colored by a node, the colors will "bleed" from one node to the next. Views colored by cell or element will be more distinct.
+
+Image shows hex mesh with node itp colors. The mesh is clipped in half to see the inside nodes of the mesh.
+<p><a href="step_01/01_hex_mesh_itp.png"> <img width="300" src="step_01/01_hex_mesh_itp.png" /> </a></p>
+
+```
+dump/ avs / 01_hex_mesh.inp / 3dmesh
+```
+
+## finish
+
+Always end a session or a file with the **finish** command and a line return after the finish command. The command line parser will not parse a command without a line return.
+
+```
+finish
+
+```

+
+
+This example will use 2 methods for creating a tet mesh from a hex mesh. 
+- Method 1 will use the mesh points to [**'connect'**](https://lanl.github.io/LaGriT/pages/docs/commands/CONNECT1.html) into a Delaunay tet mesh. 
+- Method 2 will use [**'grid2grid'**](https://lanl.github.io/LaGriT/pages/docs/commands/GRID2GRID.html) to convert hex elements into tetrahedrals.
+
+Use of **hextotet** (or **grid2grid**) to convert a 3D mesh to a tetrahedral mesh may result in a non-Delaunay tetrahedral mesh. If the target simulator is one that uses two-point flux approximation and Voronoi control volumes (FEHM, PFLOTRAN, TOUGH2) then the **connect** command should be used to create a Delaunay mesh.
+
+
+[Click here for Delaunay Definition](https://en.wikipedia.org/wiki/Delaunay_triangulation)
+
+[Click here for Voronoi Definition](https://en.wikipedia.org/wiki/Voronoi_diagram)
+
+[Click here for more details on the connect algorithm](https://lanl.github.io/LaGriT/pages/docs/connect_notes.html)
+
+
+
+
+# Method 1 using Connect Delaunay
+
+The Delaunay algorithm is applied to a set of points. In this example we will use the nodes from the hex mesh in Step 1. The point distribution will impact the success of a connected tet mesh. A point distribution where spacing varies from very small to very large can result in high aspect ratios and boundary problems. This hex mesh provides structured regular spacing and is topologically consistent and will result in a successful Delaunay connection.
+ 
+
+## Create the Hex Mesh from Step 1
+
+
+The **'infile'** command is used to read and run a LaGriT command file. In this case we read and run the same command file that was used to create a hex mesh in Step 1. 
+Use the **'cmo/status'** commands to confirm the mesh object named "3dmesh" was created.
+
+```
+infile 01_create_hex.lgi
+cmo/status/ 3dmesh / brief
+```
+
+The status report should indicate the current mesh object is a hex mesh with 1122 nodes and 800 hex elements. 
+<pre class="lg-output">
+The current-mesh-object(CMO) is: 3dmesh
+
+  1 Mesh Object name: 3dmesh
+    number of nodes =          1122        number of elements =          800
+    dimensions geometry =         3        element type =                hex
+    dimensions topology =         3        8 nodes      6 faces     12 edges
+    boundary flag =        16000000        status =                   active
+</pre>
+
+
+## Create a new mesh object with points to connect 
+
+The [**'connect'**](https://lanl.github.io/LaGriT/pages/docs/commands/CONNECT1.html) command will create connectivity from a cloud of points. There should be no duplicate points, and the **imt** material should be a single value. 
+
+Copy the hex points into a new mesh object, this removed the connectivity so new elements can be created. 
+```
+cmo / create / mo_tet
+copypts / mo_tet / 3dmesh
+```
+
+We now have multiple mesh objects that can be listed. Use **cmo/select** command to make "mo_tet" mesh object current for the next commands.
+Note the **cmo/status** command shows there are no elements in this mesh object. The "brief" option will show the mesh object summary without the long list of associated attributes.
+
+```
+cmo / list
+cmo/ select / mo_tet
+cmo/ status / mo_tet / brief
+```
+<pre class="lg-output">
+The current-mesh-object(CMO) is: mo_tet
+
+  0    Mesh Object name: -default-
+  1    Mesh Object name: 3dmesh
+  2    Mesh Object name: mo_tet
+cmo/select/mo_tet
+cmo/status/mo_tet/brief
+
+The current-mesh-object(CMO) is: mo_tet
+
+  2 Mesh Object name: mo_tet
+    number of nodes =          1122        number of elements =            0
+    dimensions geometry =         3        element type =                tet
+    dimensions topology =         3        4 nodes      4 faces      6 edges
+    boundary flag =        16000000        status =                   active
+
+</pre>
+
+Prepare the points by removing duplicates and setting imt to a single value and boundary tags to 0. The **filter** command will mark duplicate points as "dudded" points; the **rmpoint/compress** command will remove the dudded nodes from the mesh object. These commands will not make any changes if there are no duplicate points. 
+
+*Note: the special token ";" can be used to call multiple commands on the same line.*
+
+```
+# Remove duplicate points if they exist
+filter/1,0,0 ; rmpoint/compress
+
+# Set some defaults for the connect routine
+cmo / setatt / mo_tet / imt / 1 0 0 / 1
+cmo / setatt / mo_tet / itp / 1 0 0 / 0
+
+# Create Delaunay tet connectivity of all nodes in the mesh
+connect
+
+```
+
+The result of the **connect** command should show success.
+<pre class="lg-output">

+
+# Method 2 converts each hex into 5 tets 
+
+The [**'grid2grid'**](https://lanl.github.io/LaGriT/pages/docs/commands/GRID2GRID.html) is a wrapper that simplifies many of the grid-to-grid conversions. In this case we will use the option that converts each hex element into 5 tets (with no points added). This command requires the creation of a new mesh object, the new name is given first, with the source mesh object name at the end.
+
+```
+grid2grid / hextotet5 / mo_hex2tet / 3dmesh
+```
+
+Check the list of mesh objects, the new "mo_hex2tet" mesh object should now be current as the newly created object.
+Check for positive volumes and set mesh default values.
+
+```
+cmo / list
+quality
+cmo / setatt / mo_hex2tet / itetclr / 1
+resetpts / itp
+```
+
+There are now 3 mesh objects. "3dmesh" is the hex mesh created at start of this run. "mo_tet" was created with the **connect** command. "mo_hex2tet" was created by the **grid2grid/hextotet5** command.
+Note the **quality** command is evaluating the current mesh object, "cmo_hex2tet".

+</pre>
+
+Now we have two tet meshes, one created with **connect** and the other with **grid2grid**. In general, we use the connect algorithm to create Delaunay meshes using Voronoi control volumes (FEHM, PFLOTRAN, TOUGH2). Converting hex elements into tet elements will not be Delaunay and may affect results depending on the physics used. 
+
+For viewing these new meshes, we can add node and element attributes. With the following commands we add values for each tet volume and for the voronoi volume around each mesh node.
+See a list of attributes that can be created at [**`cmo/addatt`**](https://lanl.github.io/LaGriT/pages/docs/commands/cmo/cmo_addatt.html)
+
+
+```
+cmo/addatt / mo_tet / volume / tet_vol
+cmo/addatt / mo_tet / voronoi_volume / vor_vol
+
+cmo/addatt / mo_hex2tet / volume / tet_vol
+cmo/addatt / mo_hex2tet / voronoi_volume / vor_vol
+
+cmo/printatt/ mo_tet / tet_vol / minmax
+cmo/printatt/ mo_tet / vor_vol / minmax
+cmo/printatt/ mo_hex2tet / tet_vol / minmax
+cmo/printatt/ mo_hex2tet / vor_vol / minmax
+
+dump/avs/02_tet_connect.inp/mo_tet
+dump/avs/02_hex2tet5.inp/mo_hex2tet
+```
+
+We can use the **cmo/printatt** command to view the minmax values of the attributes in named mesh objects. 
+
+```
+cmo/printatt/ mo_tet / tet_vol / minmax
+cmo/printatt/ mo_tet / vor_vol / minmax
+cmo/printatt/ mo_hex2tet / tet_vol / minmax
+cmo/printatt/ mo_hex2tet / vor_vol / minmax
+```
+
+The connect mesh and the hextotet mesh have the same 1122 number of nodes. But the connectivity created 4800 tet elements with connect and 4000 for hextotet mesh. Notice the tet element minmax volumes have different results, the connected mesh has volumes all equal. For this structured point distribution, the voronoi volumes for each node have the same min max range.

+# Viewing the Tet Meshes
+
+The following images were created by using Paraview reading the AVS mesh files. Click to see full resolution images.
+
+Paraview images show tet elements colored by element volumes of connected Delaunay mesh (left) and grid2grid (right). The grid2grid view is clipped to see the internal tet elements that are larger than the tets formed at the hex corners.

+
+Paraview images show the mesh colored by node voronoi volumes. The boundary nodes will have half volumes, the corner nodes will have quarter volumes. Internal voronoi volumes are all the same. Image is clipped to show internal mesh nodes. Both meshes have the same voronoi volumes.

+
+This example will show how to use some basic commands to assign materials to mesh nodes and elements. Interpolation of materials from the hex mesh to the tet mesh is used to ensure block shaped interfaces.
+
+
+Methods include:
+
+- Set selections using [**`pset`**](https://lanl.github.io/LaGriT/pages/docs/commands/PSET.html) for mesh points and [**`eltset`**](https://lanl.github.io/LaGriT/pages/docs/commands/ELTSET2.html).
+- Regions defined by surfaces using [**`surface`**](https://lanl.github.io/LaGriT/pages/docs/commands/SURFACE.html) and [**`region`**](https://lanl.github.io/LaGriT/pages/docs/commands/REGION.html)
+- Interpolation from hex materials to tet mesh materials using [**`interpolate`**](https://lanl.github.io/LaGriT/pages/docs/commands/main_interpolate.html) 
+- Use LaGriT commands to report material node and element counts for the final mesh
+
+
+## Define Mesh Names
+
+In this example we assign materials (color) to the hex mesh, then interpolate hex mesh materials to the tet mesh. This method ensures nice interfaces between materials. If the tet mesh is colored with following methods, the tet interfaces will be ragged, with tet elements sticking out. 
+
+Define input and output file names for easy switch between mesh types. As seen here, the second set of file names are last defined and will be used. If you want to see how it looks to use the tet mesh, simply copy and paste the first 2 lines after the hex file names. 
+
+Results are shown in image at top of page. Image a. This example hex_colors.inp b. Run with tet_colors.inp c. This example using interpolation for tet_colors.inp
+
+```
+define IN_FILE 02_tet_mesh.inp
+define OUT_FILE tet_colors.inp
+
+define IN_FILE 01_hex_mesh.inp
+define OUT_FILE hex_colors.inp
+```
+
+## Read the Hex Mesh  
+
+We start with the hex mesh created in Step 1. of this tutorial. Instead of creating it again, we just read the AVS mesh file. Note the variable IN_FILE is define above as "01_hex_mesh.inp". We have given the mesh object the name mo_mat to indicate it is the mesh object we will assign materials to. You can name the mesh anything you want if it is clear and consistent with your usage.
+
+```
+read/avs/ IN_FILE / mo_mat
+cmo/status/mo_mat/ brief
+cmo/select/mo_mat
+```
+
+## Assign Materials by Selected Sets (pset and eltset) 
+
+Define some elevations for layers between top and bottom of mesh between 0. and 80.
+
+```
+define MAT1_Ztop 40.
+define MAT2_Ztop 62.
+```
+
+For the current mesh, select node sets based on the attribute zic (Z coordinate). Name the psets "pmat1", "pmat2", and "pmat3" for use in assigning materials. Note reminder the "1,0,0" refers to node numbers start, stride, stop where "0,0" indicates "all".
+
+```
+pset/pmat1/attribute zic/1,0,0/ lt MAT1_Ztop
+pset/pmat2/attribute zic/1,0,0/ lt MAT2_Ztop
+pset/pmat3/attribute zic/1,0,0/ ge MAT2_Ztop
+```
+
+Based on the set selections above, we can now assign integer values to node materials in the **imt** attribute.
+In this example ordering of assignment matters as both "pmat1" and "pmat2" overlap below zic=40. This is ok, we simply overwrite by assigning the lowest set last.
+
+```
+cmo/setatt/mo_mat/imt/ pset,get,pmat3 / 3
+cmo/setatt/mo_mat/imt/ pset,get,pmat2 / 2
+cmo/setatt/mo_mat/imt/ pset,get,pmat1 / 1
+```
+
+To assign materials to the elements, we use the psets above to create element sets. Note elements can be formed to make sure each vertice of the element is in the pset, or such that only one needs to be in the pset.
+In this example we use **inclusive** which will include more elements than the **exclusive** option.
+
+After setting the element sets, assign material integers to the **itetclr** element attribute in same order as the psets.
+
+```
+eltset/emat1/inclusive/pset,get,pmat1
+eltset/emat2/inclusive/pset,get,pmat2
+eltset/emat3/inclusive/pset,get,pmat3
+
+cmo/setatt/mo_mat/itetclr/eltset,get,emat3/ 3
+cmo/setatt/mo_mat/itetclr/eltset,get,emat2/ 2
+cmo/setatt/mo_mat/itetclr/eltset,get,emat1/ 1
+```
+
+Write a temporary file to view node and element colors so far.
+ 
+```
+dump/ tmp_layers.inp / mo_mat
+```
+
+Viewing the mesh file tmp_layers.inp we can check if node **imt** and element Materials are set as we intended. The result is a mesh with 3 layers with material 1 at the bottom and 3 at the top.
+
+These images were created from Paraview showing the mesh colored by node attribute **imt** left. The mesh is colored by element materials on the right, mesh nodes colored by **imt**. Though modeling software such as FEHM use only the node materials, viewing the mesh by element color presents a better picture. Click on images to view full resolution image.

+
+
+## Assign Materials by Surfaces
+
+
+The **region** command is extremely useful for defining nodes or elements based on surfaces or geometric shapes. Most of these are represented by their equations, but a surface can also be a mesh that is created or read from file as used in this example.  We create two surfaces using **surface/sheet/**/*mo_name* which will be used to define a region representing a fourth material. 
+
+Note. In this case we use a mesh object name that implies it is temporary and will be deleted after use. Creating naming conventions for your objects will help you to keep track of objects during the workflow.
+
+```
+cmo / create / motmp
+cmo / select / motmp
+```
+
+Create a quad mesh based on corner coordinates, since this will be used to define regions on the mesh, make sure the surface coordinates extend equal or greater to the mesh. A surface that truncates inside the mesh domain will be ill defined with respect to below or above. These two surfaces could also be created with the **surface/plane** command and used in the same way, but are internal and can not be viewed with respect to the mesh.
+
+The **brick** option for **createpts** is used to create a quad mesh from the point distribution.  The quads are converted to triangles with the **hextotet** command. After the surface is created, print the minmax coordinates and view the surface to make sure it where you want it. 
+
+```
+quadxy / 10 5 /-1. -1. 10.   /100.1 -1.  100./ &
+               100.1 51. 100./   -1. 51. 10.
+createpts/brick/xyz/ 10 5 1 /1,0,0/connect
+hextotet/4/ mosurf1 / motmp
+cmo / printatt / mosurf1 / -xyz- / minmax
+dump/ tmp_surf1.inp / mosurf1
+```
+
+Create a second surface offset from first surface by a distance of 15 in the positive direction.
+
+```
+offsetsurf/ mosurf2 / mosurf1 / 15.
+dump/ tmp_surf2.inp / mosurf2
+```
+
+View the mesh and the surfaces together to be sure it is correct. The nodes colored red in the image is the region we will set to material 4.
+
+<p>
+<a href="step_03/step_03_hex_colors_surfs.png"> <img width="420" src="step_03/step_03_hex_colors_surfs.png" /> </a>
+</p>
+
+To use the geometry commands such as surfaces and regions, FIRST make sure your mesh object is current. Otherwise, these geometry command will not be available for use on the mesh object. Use the **cmo/select** command to make sure you apply these commands to the "mo_mat" mesh object.
+
+In the previous steps we created two mesh objects, mosurf1 and mosurf2. We now tell LaGriT to use those mesh objects to define surfaces of type **sheet**. There are many types of surfaces such as cone, and box. See more at [**`surface`**](https://lanl.github.io/LaGriT/pages/docs/commands/SURFACE.html). 
+
+```
+cmo / select / mo_mat
+surface / s_mosurf1 / reflect / sheet / mosurf1
+surface / s_mosurf2 / reflect / sheet / mosurf2
+```
+
+Now that LaGriT has sheets named "s_mosurf1" and "s_mosurf2" defined for the mesh object geometry, we can use them to define a region between the surfaces. 
+The **le** and **ge** operators are used with the [**`region`***](https://lanl.github.io/LaGriT/pages/docs/commands/REGION.html) command to define regions. For instance, **ge** for a surface means the space on the same side as the surface normal direction, **le** means the space opposite of the normal direction. Use **le, ge** to include nodes equal to the surface, otherwise use **lt, gt**. 
+```
+region/ r_slant / ge s_mosurf1 and le s_mosurf2
+```
+
+Now use this region named "r_slant" to define node and elements in the slanted region. Use the **cmo/setatt** command with these sets to assign the value 4 to node **imt** and element **itetclr** arrays, but only to the defined sets. The value 4 will overwrite previous values of 1-3 set earlier.
+
+```
+pset/ pslant / region / r_slant
+eltset/ eslant / region / r_slant
+
+cmo/ setatt / mo_mat / imt / pset,get,pslant / 4
+cmo/ setatt / mo_mat / itetclr / eltset,get,eslant / 4
+```
+
+Since the materials have changed, it is good practice to update the boundary and interface attribute **itp** mesh arrays.
+Write the mesh with materials using the "OUT_FILE" variable defined at the beginning.
+
+```
+resetpts/itp
+dump / OUT_FILE / mo_mat
+cmo / status / mo_mat / brief
+```
+
+Debug hint: things often go wrong early in the script, make sure there are no errors before continuing. You can do this by adding an early finish and observing the output report. If there are no errors reported, and the mesh looks as expected, comment the **finish** command so the LaGriT command continues.
+
+```
+# Uncomment Early finish to check results 
+# finish
+```
+
+
+## Assign Materials by Interpolation
+
+If you color the tetrahedral mesh using the above steps, you might get ragged edges that do not look as nice as the colored hex mesh. And if you added refinement to your mesh, using your original coarse hex mesh colors will better preserve the layers as you intended. This will preserve the stair-step interfaces of materials
+
+It is good practice to remove mesh objects that are no longer needed. The more mesh objects that exist, the greater possibility of things getting tangled or mistakes with typos.
+ 
+```
+cmo/delete/motmp
+cmo/delete/mosurf1
+cmo/delete/mosurf2
+cmo/list
+```
+
+Now that we have a hex mesh with materials the way we like them. Read the computational tetrahedral mesh (from Step 2), and interpolate the hex (source) values to the tet mesh.
+
+
+```
+read/avs/ 02_tet_mesh.inp / mo_tet
+cmo/select/mo_tet
+```
+
+The **interpolate/map** command copies the value from the enclosing source element to the element (centroid).
+The **interpolate/voronoi** command copies the value from the nearest source node to the sink node. 
+
+```
+interpolate/map/mo_tet/ itetclr /1,0,0/ mo_mat itetclr
+interpolate/voronoi/mo_tet/ imt /1,0,0/ mo_mat imt
+```
+
+<p>Mesh left shows results if these steps are applied to the tet mesh. Mesh right shows hex mesh interpolated to tet mesh.

+ <a href="step_03/step_03_tet_colors_good.png"> <img width="350" src="step_03/step_03_tet_colors_good.png" /> </a> 
+</p>
+
+Check the interpolated materials with the **printatt** commands. There should be minmax values 1 and 4.
+
+```
+cmo/printatt/mo_tet/imt minmax
+cmo/printatt/mo_tet/itetclr minmax
+```
+
+<pre class="lg-output">
+cmo/printatt/mo_tet/imt minmax

+
+Set the boundary nodes based on these new materials and write an AVS mesh file for viewing.
+
+```
+resetpts/itp
+dump/avs/tet_interp_materials.inp mo_tet
+```
+
+
+## Report Material Quantities
+
+Sometimes it helps to see node and element material quantities before viewing the mesh. This is a good way to catch easy mistakes. These results are also useful to include in reports as part of the setup description. Scripts can be written to parse "lagrit.out" results for nice tables and other summary information.
+
+The minmax option is a quick easy way to check for mistakes. The **imt1** (same as **imt**) attribute are the node materials, so length of the array is 1122, the number of nodes in this mesh. The **itetclr** attribute are the element materials with a length of 4800, the number of elements in this mesh. As expected, they both have values from 1 to 4. 
+**Note: these material attributes must have integer numbers greater than 0**
+
+Note. Unless the tet mesh is modified to be different from the source hex mesh, they will have the same number of nodes. Only the element type and count will change.
+
+```
+cmo/select/mo_tet
+cmo/printatt/mo_tet/ imt minmax
+cmo/printatt/mo_tet/ itetclr minmax
+```
+LaGriT will show the following results.
+<pre class="lg-output">
+ATTRIBUTE NAME              MIN               MAX         DIFFERENCE    LENGTH
+ imt1                             1                4               3      1122
+
+cmo/printatt/mo_tet/itetclr minmax
+ATTRIBUTE NAME              MIN               MAX         DIFFERENCE    LENGTH
+ itetclr                          1                4               3      4800
+</pre>
+
+This command will report element volumes by material ID, default is all, but single value reports are an option.
+
+```
+quality/ volume / material
+```
+
+The summary of element volume materials should look like this:
+
+<pre class="lg-output">
+  SUMMARY VOLUME/AREA of ELEMENT COLORS for mo_tet     1      4
+...........................................................
+Color      Num. Elements   Volume          Fractional Volume
+    1        2160          0.1800000E+06     0.450000000
+    2        1140          0.9500000E+05     0.237500000
+    3         720          0.6000000E+05     0.150000000
+    4         780          0.6500000E+05     0.162500000
+ Total elements:      4800       Total Volume:  0.4000000E+06
+-----------------------------------------------------------
+      4800 total elements evaluated.
+</pre>
+
+For modeling applications such as FEHM, the node materials are used, not the elements. This **dump/zone_imt** command is part of the FEHM commands available to write material zone files. It also creates a good summary of the node materials.
+
+```
+dump/zone_imt/ tet / mo_tet
+```
+
+The summary of node counts by material will look like this:
+<pre class="lg-output">
+*********dump_material_lists********
+Minimum material ID value =      1
+Maximum material ID value =      4
+Total possible materials  =      4
+Material       1 has       468 nodes. #nodes/nnodes is   0.417112290859
+Material       2 has       270 nodes. #nodes/nnodes is   0.240641713142
+Material       3 has       204 nodes. #nodes/nnodes is   0.181818187237
+Material       4 has       180 nodes. #nodes/nnodes is   0.160427808762
+</pre>
+
+We do not currently have an easy wrapper command for a summary of voronoi volumes, but a summary can be generated by using the following commands. 
+
+1. Use the command [**`cmo/addatt`**](https://lanl.github.io/LaGriT/pages/docs/commands/cmo/cmo_addatt.html) to create a node attribute with values of voronoi volumes for each node.
+2. Create a pset for each material value.
+3. Use the [**`math`**](https://lanl.github.io/LaGriT/pages/docs/commands/MATH.html) command to sum all voronoi values in the indicated **pset,get,p1** set of nodes.
+
+*Note: the [**`loop`**](https://lanl.github.io/LaGriT/pages/docs/commands/loop.html) command can be used to loop through each of the material values.*
+
+```
+cmo addatt/mo_tet/vor_volume/vorvol
+pset/p1/attribute/imt/1,0,0/ eq 1
+math/sum/mo_tet/vol_tot/pset,get,p1/mo_tet/vorvol
+pset/p1/attribute/imt/1,0,0/ eq 2
+math/sum/mo_tet/vol_tot/pset,get,p1/mo_tet/vorvol
+pset/p1/attribute/imt/1,0,0/ eq 3

+pset/p1/attribute/imt/1,0,0/ eq 4
+math/sum/mo_tet/vol_tot/pset,get,p1/mo_tet/vorvol
+```
+
+There will be some extra LaGriT output during the run including "AMatbld3d_stor" output regarding the voronoi volumes and associated coefficients. Extra lines can be removed for a summary that looks like this:
+<pre class="lg-output">
+AMatbld3d_stor: Volume min =   6.2500000E+01
+AMatbld3d_stor: Volume max =   5.0000000E+02
+AMatbld3d_stor: Total Volume:   4.0000000E+05
+
+ THE PSET  p1  HAS        468 POINTS
+vorvol sum =   0.167500000000E+06
+
+ THE PSET  p1  HAS        270 POINTS
+vorvol sum =   0.100000000000E+06
+
+ THE PSET  p1  HAS        204 POINTS
+vorvol sum =   0.650000000000E+05
+
+ THE PSET  p1  HAS        180 POINTS
+vorvol sum =   0.675000000000E+05
+</pre>
+
+
+## finish
+
+Always end a session or a file with the **finish** command and a line return after the finish command. The command line parser will not parse a command without a line return.
+
+```
+finish

+#### LaGriT output   file: [lagrit.out](step_04/04_fehm_files.out.txt)

+
+
+LaGriT's meshing tools are tailored for geologic applications and Voronoi control volume solvers.  Though LaGriT can write files that are of general use, some are specifically designed for the FEHM porous flow and transport code. This example writes model setup files used by FEHM but can be modified for use in other simulators using Voronoi control volumes (FEHM, PFLOTRAN, TOUGH2). 
+
+- Use the tetrahedral mesh with materials created in Step 3.
+- Use [**`dump/fehm`**](https://lanl.github.io/LaGriT/pages/docs/commands/dump/DUMP3.html) to write 7 model setup files.
+- Locate and write a list of nodes representing a vertical well zone.
+- View and check the mesh quality and defined zones.
+
+The following model setup files will be written:
+-  material.zone - node zone lists for each material. Same as [**`dump/zone_imt`**](https://lanl.github.io/LaGriT/pages/docs/commands/DUMP2.html#zone)
+-  outside.zone - lists of nodes on outside boundaries such as top, bottom, and sides. Same as [**`dump/zone_outside`**](https://lanl.github.io/LaGriT/pages/docs/commands/DUMP2.html#zone)
+-  outside_vor.area - voronoi areas associated with nodes on outside boundaries
+-  multi_mat.zone - lists of node pairs connected across material interfaces (multi-material nodes) 
+-  interface.zone - lists of nodes along material interfaces (for multi-material cells seldom used with FEHM)
+-  .stor - file with voronoi control volumes associated with each node and the sparse matrix structure. Same as [**`dump/stor`**](https://lanl.github.io/LaGriT/pages/docs/commands/DUMP2.html#stor) and described at [**`stor format`**](https://lanl.github.io/LaGriT/pages/docs/STOR_Form.html)
+-  .fehm - mesh coordinates and geometry in FEHM grid format. Same as [**`dump/coord`**](https://lanl.github.io/LaGriT/pages/docs/commands/DUMP2.html#coord)
+
+
+## Read the tetrahedral mesh with materials from Example 3
+
+
+Read the mesh and check for positive volumes and expected node material values. The `quality` command shows all cells with the same volume as expected. The [**`cmo/printatt`**](https://lanl.github.io/LaGriT/pages/docs/commands/cmo/cmo_printatt.html) command is recommended for checking mesh attributes at important steps in the input file. The keyword **minmax** will display the min and max values of mesh attributes for easy confirmation of values. As expected, the node attribute has material values 1 to 4. (Created in [Step 3](../step_03.md)).
+
+Note. You can add a `finish` command after this section and exit early to be sure all is as expected. Then comment out or remove the temporary finish. 
+
+```
+read / avs / tet_interp_materials.inp / mo_tet
+quality
+cmo/printatt/mo_tet/imt minmax
+```
+
+<pre class="lg-output">

+
+ATTRIBUTE NAME         MIN               MAX         DIFFERENCE    LENGTH

+</pre>
+
+The following commands are almost always used in preparation of writing FEHM model files. They are not always needed but using them will cause no harm. It is good practice to include in case they are needed.
+
+- Set cell colors to 1. FEHM uses properties assigned to the voronoi volumes around the mesh vertices (nodes). Though cell colors are better for images, they are not used in FEHM simulations. It is good practice to set the element attribute **itetclr** to 1. This avoids routines looking for multi-material elements.  
+
+- Reset the itp array when materials are changed. This array is important to some routines. 
+
+- The [**`resetpts/parent`**](https://lanl.github.io/LaGriT/pages/docs/commands/RESETPT.html) command will remove the parent-child relationship is established in the settets command.
+
+- Sometimes during the meshing process there will be duplicate or double-defined nodes created. Use the `filter` command to find and tag nodes as `dudded`. 
+
+- IMPORTANT: Nodes tagged for removal will not be deleted from the mesh object until `rmpoint/compress` is called. This will remove any dudded nodes and adjust the connectivity.
+
+```
+cmo/select/mo_tet
+cmo/setatt/mo_tet itetclr 1
+resetpts/itp
+
+cmo/select/mo_tet
+resetpts/parent
+filter/1,0,0
+rmpoint/compress
+```
+
+## Write default FEHM files
+
+By default, all 7 FEHM files are written with rootname "tet". 
+
+```
+dump/fehm/ tet /mo_tet/ keepatt
+dump/avs/tet_fehm.inp/mo_tet
+```
+
+Note: We normally do not use multiple material regions for FEHM so the `interface.zone` will be empty. (If itetclr=1 and resetpts/itp was called). If the node imt materials are a single value, the `multi_mat.zone` will also be empty.

+The `_material.zone` file contains zones listing node ids for each integer value found in the mesh **imt** attribute.  This is a single file separated by id, "nnum" and total for each list. See right image below.
+
+The **keepatt** keyword will keep attributes normally deleted after writing files.  The 6 outside attribute names are added to the mesh object with the names and integer id based on normal directions:
+- 1 = top = top = positive z direction (0,0,1)
+- 2 = bottom = bottom = negative z direction (0,0,-1)
+- 3 = left_w = left or west = negative x direction (-1,0,0)
+- 4 = front_s = front or south = negative y direction (0,-1,0)
+- 5 = right_e = right or east = positive x direction (1,0,0)
+- 6 = back_n = back or north = positive y direction (0,1,0)
+
+Note: A node can occur in multiple zones. For instance, a node located on a top corner of the mesh can be found in zones for top, front_s, and left_w. See left image below.

+The output from the `dump/fehm` command generates output that is useful for checking the final mesh and to share in reports.
+The following is a table reporting the node count for each material. In this case the bottom layer material 1 has the most nodes and the fault material 4 has the fewest as expected.

+The routine `AMatbld3d_stor` generates a report summary regarding the voronoi volumes and number of coefficients.

+</pre>
+
+Negative coefficients can occur on non-convex boundaries or with unstructured complex meshes. If they occur, these negative coefficients are stored in a node attribute named `ccoef`. Viewing this attribute can provide help in finding areas of the mesh that need adjustment. It is possible that a mesh has ccoef values at or very close to zero, in which case they can be ignored. The following pset commands can help find ccoef values of concern.
+
+Note. The `cmo/addatt` command is called but will not be used if the `AMatbld3d_stor` routine creates it. We create it just in case it does not exist so the commands using it do not fail with an Error.
+
+```
+cmo/addatt/mo_tet/ccoef/VDOUBLE/scalar/nnodes/linear/
+cmo select mo_tet
+pset pin attribute itp   1,0,0 lt 10
+pset pneg attribute ccoef 1,0,0 lt -.0001
+pset pBAD inter pin pneg
+cmo printatt mo_tet ccoef minmax
+cmo printatt mo_tet -all- minmax
+```
+
+## Create zone file for vertical well
+
+
+Zones for simulations can be created and written by using the `pset` commands. In this example a single column of nodes is selected to represent a well. There are numerous ways to create a set, in this example we use a geometric region in box shape. A cylinder would also work.
+
+Regions are defined by surfaces, here we use a box surface around the node column at 50,10 X,Y. The region is defined as an inside the box surface but can be combined with other surfaces for more complex regions. A pset is formed of all points within the `r_bx` region and written to a zone file.
+
+ Write the list of nodes to a zone file
+ Assign a zone number larger than max material
+
+```
+cmo select mo_tet
+surface / s_box / reflect / box / 49.5 19.5 -1. / 50.5 20.5 100.
+region/ r_box / le s_box
+pset/pwell/ region / r_box
+
+# check extents of the well nodes
+cmo/printatt/mo_tet/-xyz/ minmax/ pset,get,pwell
+
+pset/pwell/ zone / tet_well_nodes.zone / ascii / 11
+```
+
+There should be 13 nodes found within the region. Check the xyz extents to see that one column is selected at the intended elevations.
+
+<pre class="lg-output">

+</pre>
+
+## Add Mesh Attributes for Mesh Views
+
+When inspecting the mesh and to create informative figures, it helps to add attributes. For this example, a node attribute named **iwell** is created and assigned the value 11. The elevation is nice to see and is created by copying the **zic** attribute to a new attribute named **elev**.
+
+
+
+
+```
+cmo/addatt/mo_tet iwell/VINT/scalar/nnodes/linear/permanent//0
+cmo/setatt/mo_tet/ iwell /pset,get,pwell/ 11
+cmo/printatt/mo_tet/ iwell/ minmax
+
+cmo/addatt/mo_tet elev/VDOUBLE/scalar/nnodes/
+cmo/copyatt/ mo_tet mo_tet / elev zic
+
+cmo/set_id/mo_tet/node/ id_node
+
+dump/avs/tet_attributes.inp/ mo_tet
+cmo/printatt/mo_tet/-all- minmax
+cmo/status/mo_tet
+```
+
+The command `cmo/printatt` is used with the **minmax** keyword to check attributes and values in the mesh object. In this example, added attributes include the 6 boundary directions, iwell, elev, and id_node.

+## Check Well Zone
+
+It can be difficult to view mesh nodes within a mesh, it helps to write the points as a separate view file. The mesh nodes (without elements) are copied to a `motmp` mesh object which has all nodes removed except the well nodes. These can be written to any file format, but the AVS UCD pnt type is recognized by Paraview for easier point displays. This is part of the `dump/avs` options that can be set after the mesh object name.
+
+These options are provided to enable a user the flexibility of writing ASCII files with desired information. For this example, "1 3 1 0 0" means 1= nodes are written, 3 = elements are written of type "pnt", 1 = node attributes are written, 0 = cell attributes are not written, and 0 = model attributes are not written. 
+
+
+```
+cmo/create/motmp
+copypts/motmp/mo_tet
+cmo/select/motmp
+pset/pduds/attribute iwell/1,0,0/ ne 11
+rmpoint/pset,get,pduds
+rmpoint/compress
+
+dump/avs/tet_well_pnts.inp/ motmp / 1 3 1 0 0
+cmo/printatt/motmp/-all- minmax
+```
+These Paraview images show the mesh clipped to the well (left) and the well nodes (right). Check the well nodes are located correctly with respect to the mesh materials. Use Paraview to Query a well node to check attributes such as **imt** material and **elev**. Note when the well points are subset from the full mesh, the node ID changes but the attribute **node_id** has the original mesh node ID saved.
