>> The **cmo** command operates on the Mesh Object(MO). There can be many Mesh
Objects in the code for a given problem. Only one of these Mesh Objects may by
the Current Mesh Object. There is also one Default Mesh Object which is used
as the template for generating new Mesh Objects.

> FORMAT:

Add a user defined attribute to a Mesh Object

[**cmo**/**addatt**](cmo/cmo_addatt.html) /mo_name/att_name/type/rank/
length/interpolate/persistence/ioflag/value

[**cmo**/**addatt**](cmo/cmo_addatt.html) /mo_name /keyword /
keyword_parameters

Give the sink mesh the same set of attributes as the source mesh (with
unitialized values)

**[cmo/attribute_derive](cmo/cmo_att_derive.html)**/sink_mo/[src_mo]

Change two meshes so they both share the same set of attributes (taking the
union of their sets of attributes)

**[cmo/attribute_union](cmo/cmo_att_derive.html)**/mo_name_1/mo_name_2

Shorten all memory managed arrays associated with mo_name to their actual
lengths

**[cmo/compress](cmo/cmo_compress.html)**/mo_name/

Associate the surface constraint information of the mesh object cmo_src with
cmo_sink:

[**cmo/constraint**/](cmo/cmo_constraint.html)cmo_sink/cmo_src

Copy master_mo to mo_name:

**[cmo/copy](cmo/cmo_copy.html)**/mo_name/master_mo/

Copy a mesh object attribute:

**[cmo/copyatt](cmo/cmo_copyatt.html)**/cmosink/cmo_src/att_nam_sink/att_nam_src

Create a new mesh object:

**[cmo/create](cmo/cmo_create.html)/**mo_name/[npoints/nelements/mesh-type]

Delete an existing mesh object:

**[cmo/delatt](cmo/cmo_delatt.html)/**mo_name/att_name/

Delete an existing mesh object even it has 'permanent' persistance:

**[cmo/DELATT](cmo/cmo_delatt.html)/**mo_name/att_name/

Copy the structure of master_mo to mo_name, but copy no data:

**[cmo/derive](cmo/cmo_derive.html)**/mo_name/master_mo/

Associate the geometry named geometry_name with the mesh object mo_name:

**[cmo/geometry](cmo/cmo_geom.html)/**mo_name/geometry_name

Print the memory length of attribute att_name for Mesh Object, mo_name:

**[cmo/length](cmo/cmo_length.html)**/mo_name/att_name/

List all mesh objects:

**[cmo/list](cmo/cmo_list.html)**

Adjust the memory manages arrays associated with mo_name to the

lengths required by number_nodes and number_elements:

[**cmo/memory**/ ](cmo/cmo_memory.html)mo_name/number_nodes/number_elements /

Modify an attribute parameter value:

[**cmo**/**modatt**/](cmo/cmo_modatt.html)mo_name/att_name/field_name/new_fiel
d/

Change the name of a mesh object:

**[cmo/move](cmo/cmo_move.html)**/mo_name /master_mo /

Adjust the memory length of mo_name based on the values of nnodes and

nelements:

**[cmo/newlen](cmo/cmo_newlen.html)**/mo_name/

Print the value of an attribute:

**[cmo/printatt](cmo/cmo_printatt.html)**/mo_name/att_name|-**all-**|**-xyz-**|**nod **/ [**minmax**|**list**|**value**]** **/[ifirst,ilast,istride]

Read values for an attribute from a file:

**[cmo/readatt](cmo/cmo_readatt.html)**/mo_name/att_name/[...]/operation/file_name

Release a mesh object (same as delete):

**[cmo/release](cmo/cmo_release.html)**/mo_name/

Make mo_name the active mesh object:

**[cmo/select](cmo/cmo_select.html)**/mo_name/

Set the value of an attribute:

**[cmo/setatt](cmo/cmo_setatt.html)**/mo_name/att_name/ifirst,ilast,istride/value

Create an integer attribute that contains the node or element number:

**[cmo/set_id/](cmo/cmo_setid.html)**mo_name/**node** |**element** |**both**/[att_nam1]/[att_nam2]

Print the mesh object status (all attributes and values of scalars)

[**cmo/status**/](cmo/cmo_status.html)mo_name/[**brief**]

Verifie that memory allocation of Mesh Object mo_name is consistent:

**[cmo/verify](cmo/cmo_verify.html)**/mo_name/   
&nbsp_place_holder;

CONVENTION: As a result of any command that generates a new mesh object, the
newly generated mesh object becomes active. As a result of any command the
changes a mesh

object (e.g. copyatt) the changed mesh object becomes
active.&nbsp_place_holder; Use cmo/select to explicitly

specify the active mesh object.
