*set_meshfaceparams

Syntax

*set_meshfaceparams face_index shape_type elem_type alg_type elem_size smooth_method smooth_tol size_control skew_control

Type

HyperMesh Tcl Modify

Description

This command sets the face-specific parameters for the automeshing module.

Inputs

face_index

The index of the surface face under consideration.

shape_type

Determines the surface-based mesh generation algorithm to use when creating elements on the face. Valid values are:

• 1 – autodecide
• 2 – map as rectangle
• 3 – map as triangle
• 4 – map as pentagon
• 5 – advancing front

elem_type

The type of elements to create. Valid values are:

• 0 - trias
• 1 - quads
• 2 - mixed
• 3 - right trias
• 4 - quads only

alg_type

0 – Standard surface meshing

1 – Meshing with flow "align" control

3 – Meshing with flow "align" and "size" control

elem_size

Reserved for future use. Must be set to 0.

smooth_method

The smoothing method to use during the meshing process. Valid values are:

• 0 – autodecide
• 1 – size-corrected
• 2 – shape-corrected

smooth_tol

The automesher applies the smoothing algorithm until the largest adjustment made to a nodal position is less than this value. Valid vales are > 0.0.

size_control

Determines if uniform size elements should be created in mapping algorithms. Valid values are:

• 0 – Do not create uniformly-sized elements.
• 1 – Create uniformly-sized elements.

skew_control

Determines if optimal shape elements are created in mapping algorithms. Valid values are:

• 0 – Do not optimize element shapes.
• 1 – Optimize element shapes.

Example

To specify meshing parameters on face 0 of a surface for a quad dominant mesh with no size or skew control:

*set_meshfaceparams 0 1 1 0 0 0 0.1 0 0
