Syntax

*interactivemeshelems markmask elementsize elem_type elem_type2 size_control skew_control break_connect angle

Type

HyperMesh Tcl Modify Command

Description

Brings all marked elements into the automeshing module and prepares them for processing, enabling the use of all restricted module commands.

Inputs

markmask

The elements to be meshed.

elementsize

The default element edge size used to calculate element densities along the edges (where 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

size_control

Determines if uniform size elements in mapping algorithms should be created.

• 1 = yes
• 0 = no

skew_control

Determines if optimal shape elements in mapping algorithms should be created.

• 1 = yes
• 0 = no

break_connect

Determines if connectivity will be broken along shared edges between elements when a different element size is chosen.

• 1 = yes
• 0 = no

Element size along shared edges cannot be changed.

angle

Determines the angle between two edge segments when the vertex is created.

Example

In this example, the automeshing module processes two separate groups with four and six elements each (each group forms a quad with four edges). To generate a mesh for each group, the automeshing module sets up values for the element densities and biasing with the *set_meshedgeparams command. Automeshing parameters for each group are specified with the *set_meshfaceparams command. Prior to meshing, parameters for the first group were changed. This required additional setedgeparams calls for four edges. Each group of elements is sent to the *automesh command so it can determine the appropriate meshing algorithm and create an all-quads mesh. Two meshes are then saved to theHyperMesh database. The automeshing module clears from its memory any information regarding the current group so that a new group can be processed.
