*solidmap_solids_begin

Starts a multiple-solid solidmap command block.

Syntax

*solidmap_solids_begin mark_id options elem_size

Type

HyperMesh Tcl Modify

Description

This command is used by the multi-solid mapping algorithm to indicate the beginning of a solid mapping command block. It must be paired with a *solidmap_solids_end command.

The commands below can appear in a multi-solids solidmap command block between *solidmap_solids_begin and *solidmap_solids_end:
*solidmap_solids_set_density
*solidmap_solids_set_elemsize
*solidmap_solids_set_face_params
*solidmap_solids_set_mapface

Inputs

mark_id
ID of the mark containing the solids to mesh. Valid values are 1 and 2.
options
Flags that indicate different options for solid mapping. Bit values are used and the value is a sum of all the options. Any bits not listed below are unused or for internal use (e.g. called in other commands) and are always internally set to their required values. Setting them to 0 is recommended, but not mandatory.
Bit0
0 – Reserved, must be set to 0.
Bit1
0 – New elems are organized to the solid component.
2 – New elems are organized to the current component.
Bit2
0 – Reserved, must be set to 0.
Bit3
0 – Create elems when calling *solidmap_solids_end .
8 – Do not create elems when calling *solidmap_solids_end (for expert users only).
Bit4
0 – Create layered solid elements.
16 – Create layered shell elements.
Bit5,6
0 – Auto decide
32 - Do not use the fast method
64 - Use the fast method
96 - Unused
Bit8
0 – No additional smoothing steps will occur.
256 – Perform extra smoothing steps.
Bit9,10,11
2D elem type 1 and 2 passing to the internal call to *defaultremesh when per face meshing parameters are not available:
  • 0 – Tria
  • 512 – Quad
  • 1024 - Mixed
  • 1536 - R-tria
  • 2048 - Quad only
Bit13
0 – Keep shell meshes on input geometry.
8192 – Remesh shell meshes on input geometry.
Note: Solid elems on input solids are always deleted.
Bit14
0 – Normal meshing situations.
16384 – Create internal meshing sequencing structure only. Do not create mesh and internal meshing structure (for expert users only).
Bit15
0 - Do not use meshing parameters saved to the solid map attributes on the geometry.
32768 – Use meshing parameters saved to the solid map attributes on the geometry.
Bit16
0 – Make the reparameterization of along faces more orthogonal.
65536 – Make the reparameterization of along faces more like parallelograms
Bit17
0 – Do not use per edge/face saved meshing parameters.
131062 – Use per edge/face saved meshing parameters.
Bit18
0 – Stop meshing when elems with negative Jacobian are generated.
262144 – Continue meshing regardless of the elem quality.
elem_size
The default element size used when the per edge/face meshing parameters are not available.

Example

To mesh solids 32 and 41 with a default elem size of 2.0 except on edges 2 and 4 which should have an elem size of 1.0:

*createmark solids 1 32 41
*solidmap_solid_begin 1 0 2.0
*createmark lines 1 2 4
*solidmap_solids_set_elemsize 1 1.0
*solidmap_solid_end

Errors

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