*hm_failed_elements_cleanup

Cleans up the mesh by eliminating reversed and small sized elements. May create new elements instead of reversed.

Syntax

*hm_failed_elements_cleanup markmask elem_type min_elemsize max_feature_angle max_reverse_angle

Type

HyperMesh Tcl Modify

Description

Cleans up the mesh by eliminating reversed and small sized elements. May create new elements instead of reversed.

Inputs

markmask: Elements of the original mesh.
Elem_type: Determines the type of new elements:; 0 – trias; 1 – mixed type (quads and trias)
min_elemsize: Determines minimum element size of elements in the mesh after cleanup.
max_feature_angle: Determines mesh feature angle for keeping features when possible after cleanup.
max_reverse_angle: Determines maximum angle between adjacent element normals for reversed elements detection.

Example

To eliminate elements in the displayed tria mesh with size less than 1.5, remove reversed elements with adjacent normals greater than 150 degrees, trying to keep features greater than 60 degrees:

*createmark(elements,1) displayed
*hm_failed_elements_cleanup(1, 0, 1.5, 60, 150)

The *createmark() command is required.

Errors

None.
