Creating ACIS Geometry From Meshhammer

Note: These features are under development. The command to enable or disable features under development is:

     Set Developer Commands {On|OFF}

Using the Acis options (in red) in the commands below will produce ACIS geometry instead of mesh-based geometry. ACIS geometry is generally more desirable than mesh-based geometry because it can be modified easily.

Importing a Mesh

Import Mesh Geometry '<exodusII_filename>' [Block <id_range>|ALL] [Unique Genesis IDs] [Start_id <id>] [Use [NODESET|no_nodeset] [SIDESET|no_sideset] [Feature_Angle <angle>] [LINEAR|Gradient|Quadratic|Spline|Acis] [Deformed {Time <time>|Step <step>|Last} [Scale <value>] ] [MERGE|No_Merge] [Export_facets <1|2|3>] [Merge_nodes <tolerance>]

This command tries to associate the mesh to the ACIS geometry that is created. If the association fails, the mesh ends up as free mesh. For more information on this command see: Importing Exodus II Files

Existing Mesh - Create Mesh Geometry

 Create Mesh Geometry {Hex|Tet|Face|Tri|Block} <range> [Feature_Angle <angle=135>] [Acis] [Keep]

This command tries to associate the mesh to the ACIS geometry that is created. If the association fails, the mesh ends up as free mesh. For more information on this command see: Free Meshes

Existing Mesh - Create Geometry

 Create Geometry {Hex|Tet|Face|Tri} <id_range>

These two commands do not use blocks, sidesets, nodesets or a user-specified dihedral angle to create vertices, curves, and surfaces. These commands use a proprietary third-party routine to create geometry. They also do not associate the mesh to the ACIS geometry that is created.
