*blmesh_2d_input

Syntax

*blmesh_2d_input_nonbl fixed_entity_type fixed_mark_id float_entity_type float_mark_id float_mode

Type

HyperMesh Tcl Modify

Description

Specifies non-boundary layer input for *bl_mesh2d2 and *bl_mesh2d_computeblthickness.

If *blmesh_2d_input_nonbl is not called before either command, then all edges of the selected region are considered as boundary layer edges.

Inputs

fixed_entity_type: The type of entities to use for the fixed non-boundary layer. Valid values depend on the base_entity_type value specified in *bl_mesh2d2.; If base_entity_type is surfs, then the only valid value is lines.; If base_entity_type is elems, then the valid values are elems or nodes. For elems, only plotel elements are allowed.
fixed_mark_id: The ID of the mark containing the fixed entities. Valid values are 1 and 2.
float_entity_type: The type of entities to use for the float non-boundary layer. Valid values depend on the base_entity_type value specified in *bl_mesh2d2.; If base_entity_type is surfs, then the only valid value is lines.; If base_entity_type is elems, then the valid values are elems or nodes. For elems, only plotel elements are allowed.
float_mark_id: The ID of the mark containing the float entities. Valid values are 1 and 2.
float_mode: Option to specify behavior of float non-boundary layer entities.; 0 - Do nothing special.; 1 - Use remesh option.

Examples

To create a 5 layer boundary mesh with a quad dominated mesh of size 2.0 on surface 10, with the first layer being 0.15 thick and a growth rate of 1.2, using boundary layer elements 10 and 11 as fixed and 12 and 13 as float, and non-boundary layer elements 1 and 2 as fixed and 5 and 6 as float:

*createmark elems 1 10 11
*createmark elems 2 12 13
*blmesh_2d_input_bl elems 1 elems 2
*createmark elems 1 1 2
*createmark elems 2 5 6
*blmesh_2d_input_nonbl elems 1 elems 2 1
*createstringarray 2 "element_size: 2.0" "element_type: quads"
*createmark surfs 1 10
*blmesh_2d2 surfs 1 5 0.15 1.2 1 2 2

Errors

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

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