HyperMesh Tcl Modify Command

Creates a rigid body mesh on surfaces.

mark_id: The ID of the mark containing the surfaces to mesh. Valid values are 1 and 2.
min_size: The minimum element size.
max_size: The maximum element size.
max_chordal: The maximum allowed chordal deviation.
max_angle: The maximum feature angle.
remesh: 0 - Delete existing elements before mesh; 1 - Do not delete existing elements before mesh
mesh_type: 0 - Trias; 1 - Mixed
elem_comp: 0 - Organize elements in current component; 1 - Organize elements in surface component(s)
elem_order: 1 - First; 2 - Second
shared_edge_flag: 0 - Allow node movement across shared edges, and ignore chordal deviation; 1 - Do not allow node movement across shared edges, and ignore chordal deviation; 2 - Allow node movement across suppressed edges, and ignore chordal deviation; 3 - Allow node movement across shared edges, and keep chordal deviation; 4 - Do not allow node movement across shared edges, and keep chordal deviation; 5 - Allow node movement across suppressed edges, and keep chordal deviation

To create a first order rigid body mesh on surfaces 1-10, with minimum size of 0.5 and maxmium size of 30,0:

*createmark surfs 1 1-10
*rbody_mesh 1 0.5 30 0.1 15 1 1 1 1 2

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
