*cadwrapper

Wraps the geometry.

Syntax

*cadwrapper entity_type mark_id string_options

HyperMesh Tcl Modify Command

Wraps the input entities and provides additional functionalities to remove nodes, fix quality, or split tria elements.

entity_type

The type of the input entities. Valid values are elements and FE surfaces.

mark_id

The ID of the mark containing the input entities. Valid values are 1 and 2.

string_options

The string defining which operation to perform and the corresponding parameters.

To remove internal nodes from selected elements:

"tri: rmnodes"

To fix quality:

"rmx2d: angle=<value> prx=<value> ar=<value> szmin=<value> clsfy2d"

To wrap input:

"wrap2d: combo=<value> angle=<value> prx=<value> ar=<value> szmin=<value> clsfy2d leak=<value> sz2rm=<value> iter=<value>"

angle: Fix dihedral angle elements below defined angle.
prx: Fix proximity elements below defined value.
ar: Fix aspect ratio above defined value.
szmin: Fix elements below edge length below defined value.
clsfy2d: Include this string if patch elements in gap needs to be organized in neighboring components, otherwise those will be placed in new component.
iter: Number of iterations for fixes.; iter = 0 - Only topological fixes are applied; 0 < iter < 99 - Topological fixes and mesh level fixes are applied; 99 < iter < 200 - Topological fixes, mesh level fixes and reruns of wrapping are applied

To wrap the input entities:

*createmark elems 1 all
*cadwrapper elems 1 "wrap2d: combo=1 ar=100 angle=2 sz2rm=20 sz2split=20 clsfy2d iters=99"

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

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