Description

Meshes a selection of surfaces using saved or default parameters and various options.

Inputs

mark_id
The ID of the mark containing the surfaces to mesh. Valid values are 1 and 2.
elem_size
The default element size used to calculate element densities along edges (when necessary).
elem_type
Flag indicating the elements generated for mapped meshing algorithms. Valid values are:
  • 0 - trias
  • 1 - quads
  • 2 - mixed
  • 3 - right trias
  • 4 - quads only
elem_type_2
Flag indicating the elements generated for free meshing algorithms. Valid values are:
  • 0 - trias
  • 1 - quads
  • 2 - mixed
  • 3 - right trias
  • 4 - quads only
previous_settings
Flag indicating whether to break, keep or redo connectivity between neighboring surfaces. Valid values are:
  • 0 - Keep previous settings and do not break connectivity between neighboring surfaces.
  • 1 - Break connectivity between neighboring surfaces.
  • 2 - Keep connectivity between neighboring surfaces.
  • 3 - Redo connectivity between neighboring surfaces by expanding surface selection by one layer of adjacent surfaces.
comp_mode
Parameter specifying how entities are organized into components:
  • 0 - Elements are created in the current component.
  • 1 - Elements are created in the same components as their parent surfaces.
size_control
Flag indicating whether to create uniformly sized elements. Valid values are:
  • 0 - Do not create uniformly sized elements.
  • 1 - Create uniformly sized elements.
skew_control
Flag indicating whether to create optimally shaped elements when using mapping algorithms. Valid values are:
  • 0 - Do not create optimally shaped elements.
  • 1 - Create optimally shaped elements.
mesh_type
Parameter specifying the meshing algorithm for edge/surface meshing. Valid values are:
  • 1 - Standard edge meshing.
  • 2 - Chordal deviation edge meshing.
  • 3 - Proximity based surface meshing.
  • 4 - Proximity and curvature based surface meshing.
  • 5 - Curvature based surfaced meshing.
  • 6 - Proximity and curvature based meshing with free edge deviation.
  • 7 - Curvature based surface meshing with free edge deviation.
  • 11 - Standard edge meshing with flow "align" control.
  • 12 - Chordal deviation edge meshing with flow "align" control.
  • 14 - Standard edge meshing with flow "align" and "size" control.
min_size
The minimum edge size for chordal deviation meshing. Ignored otherwise.
max_size
The maximum edge size for chordal deviation meshing. Ignored otherwise.
chordal_dev
The chordal deviation value for chordal deviation meshing. Ignored otherwise.
max_angle
The maximum angle (in degrees) between edges for chordal deviation meshing. Ignored otherwise.

Examples

To create quads using a default edge size of 1.0 for the surface with ID 3:
*createmark surfaces 1 3
*defaultmeshsurf 1 1 1 1 1 0 0 0 1 0 0 0 0
To create mixed type elements for the size controlled mapping algorithm using tria transitions, trias for free mesh and chordal deviation edge meshing for surfaces 3, 5 and 6:
*createmark surfaces 1 3 5 6
*defaultmeshsurf 1 1 2 0 1 0 1 0 2 0.5 30 0.1 15

Errors

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:
if { [ catch {command_name...} ] } {
   # Handle error
}
