*autotopocleanup2

Performs automatic preparation of a model’s topology for meshing, using specified element size and element quality criteria.

Syntax

*autotopocleanup2 *autotopocleanup2 mark_id criteria_filename param_filename ?do_midmesh=<value>? ?extract_midsurface=<value>?

Type

HyperMesh Tcl Modify Command

Description

Performs automatic preparation of model’s topology for meshing, using specified element size and element quality criteria. These criteria may include geometry feature recognition (fillets, holes, beads, flanges, etc.), the topology simplification, cleaning of small features, etc. The parameters controlling the topology cleanup stages and tools are given as a set of topology cleanup parameter.

In comparison with *autotopocleanup, the *autotopocleanup2 by default excludes some cleanup operations even if they are set in the input parameters. Currently, the direct midmesh option is excluded by default.

Inputs

mark_id: The ID of the mark containing the input surfaces. Valid values are 1 and 2.
criteria_filename: The path to the file with element quality criteria. If the quality criteria file has been defined using *readqualitycriteria or *setqualitycriteria commands, the value of this option can be set to “dummy”.
param_filename: The path to the file with topology cleanup parameters. By default, the midmesh operation is ignored even if enabled in the parameters file. If the cleanup parameters file has been defined using *readbatchparamsfile , *batchparams_update, *createcleanupparamsfromstrings, or *create_batch_file commands, the value of this option can be set to “dummy”.
do_midmesh=<value>: Controls the use of “allow midmesh” parameter given in the input parameters file.; 0 – Disabled.; 1 – Enabled.
extract_midsurface=<value>: Controls the use of “extract midsurface” parameter given in the input parameters file.; 0 – Disabled.; 1 – Enabled.

Examples

To perform topology cleanup of all displayed surfaces using element quality criteria nvh10.criteria and quality parameters file nvh10.param:

*createmark surfaces 1 "displayed"
*autotopocleanup 1 "nvh10.criteria" "nvh10.param"

To perform topology cleanup of all displayed surfaces using element quality criteria and quality parameters set beforehand::
