<h2 class="uk-modal-title">Mesh Design, why does it matter?</h2>
|
|
<p>
|
|
The mesh design is chosen with consideration of the physics to be modeled, mesh size restrictions (number of degrees of freedom)
|
|
versus mesh resolution needed for model features, and the mesh and model information needed by the model application.
|
|
<br/><br/>
|
|
For modeling applications with complex stratigraphy, depending on the mesh, you can get a stable but inaccurate solution
|
|
to the physics (Zyvoloski and Vesselinov, 2006). Choose a mesh design and meshing method that gives the best performance from
|
|
the modeling application possible, with respect to the difficulty in generating the mesh.
|
|
<br/><br/>
|
|
LaGriT is used to generate meshes with control volume discretization such that the underlying control volumes are Voronoi
|
|
tessellations. Developed by Los Alamos National Laboratory as open source software, LaGriT provides a variety of meshing
|
|
tools with capabilities specific to geologic applications and Voronoi control volume solvers. Examples of methods used
|
|
for geologic applications include unstructured and structured, both with adaptive refinement to geological features.
|
|
The unstructured approach allows the creation of meshes that exactly conform to the geometric model, but
|
|
requires some expertise in building the mesh such that it will also meet the Delaunay criteria. The easier
|
|
method is to use a structured mesh with fine resolution, or a coarser mesh that uses octree refinement to increase
|
|
resolution in user specified regions of interest. These result in stair-stepped geometries instead of smooth, but can
|
|
be acceptable for where the geometry spacing is small relative to the full model domain. (Sentis and Gable, 2017).
