Description
Use this command to set a limited set of cleanup parameters directly in the command file for use with *autotopocleanup. Only a few automatic cleanup options are used; others are switched off or used with default parameters.
Inputs
- element_size
- The target mesh element size.
- element_type
- Mesh element types:
- 0 – triangle
- 1 – quadrilateral
- 2 - mixed
- feature_angle
- Elements feature angle used for features definition.
- pinholes_diameter
- Maximum diameter of the holes to be removed (filled).
- layers_around_holes
- Target number of layers of quadrilateral elements around the round holes (usually it is 0, 1, 2)
- nodes_around_holes
- Minimum number of nodes (element links) for round holes.
- beads_suppr_height
- Maximum height of beads to be totally suppressed (removed).
- Max_edge_fillets_radius
- Maximum radius of edge fillets to be removed (converted to hard corners).
Examples
To perform topology cleanup of all displayed surfaces using element quality criteria from
the file nvh10.criteria as well as the following following target
cleanup parameters:
- Element size – 10 mm
- Element type – mixed
- Element feature angle - 30 degrees
- Remove holes with diameter less than 8 mm
- Create 2 layers of quad elements around holes
- Keep minimal 6 element links for the holes
- Remove edge fillets with radius less than 9.0 mm
*create_batch_file(10,2,30,8,2,6,9 )
*createmark(surfaces,1) "displayed"
*autocleanup( 1, "nvh10.criteria" )
The cleanup parameters are deleted just after each use, so they must be set before every use.
