*batchmesh_mc

Syntax

*batchmesh_mc mark_id entity_type entity_mark_id options

Type

HyperMesh Tcl Modify

Description

Meshes geometry using BatchMesh mesh controls.

Currently, to undo this command, call *rejectbatchmesh with no parameters. Reject is possible only if Bit0 is set to 0 for the options argument. Undo is also not possible after any other command is called.

Inputs

mark_id

The ID of the mark containing the mesh controls to use. Valid values are 1 and 2.

entity_type

The entity type for the model control on-the-fly selection. Valid values are surfaces, comps and regions.

This is ignored, if the model control selection is set directly in the model mesh control.

entity_mark_id

The ID of the mark containing the model control on-the-fly selection. Valid values are 1 and 2.

This is ignored, if the model control selection is set directly in the model mesh control.

options

A flag that indicates the advanced options. Bit values are used and the value is calculated as (1*Bit0 + 2*Bit1 + 4*Bit2 + 8*Bit3 + 16*Bit4 + 32*Bit5 + 64*Bit6 + 128*Bit7).

Bit0: Allow reject.

0 – Save model to allow reject.

1 – Do not save model to allow reject.

Bit1: Overlapping selection behavior.

0 – Allow overlapping selections. The first mesh control referencing the entity is used and that entity is ignored in subsequent mesh controls.

1 – Do not allow overlapping selections and return an error.

Bit2: Mesh connectivity.

0 – Keep connectivity with existing mesh.

1 – Break connectivity with existing mesh.

Bit3: Mesh controls order.

0 – Apply mesh controls by element size.

1 – Apply mesh controls by increasing ID.

Bit4: Intermediate rollback.

0 – Do not allow intermediate rollback.

1 – Allow for intermediate rollback of failed BatchMeshing steps that worsen quality by saving an intermediate model after each step to a temp directory.

Bit5: Intermediate rollback data.

Valid only when Bit4 is 1.

0 – Delete the intermediate model and log files.

1 – Keep the intermediate model and log files.

Bit6: Plot elements.

0 – Keep plot elements.

1 – Delete plot elements before meshing.

Bit7: Delete elements unassociated to geometry.

0 – Keep unassociated elements.

1 – Delete unassociated elements before meshing.

Examples

*createentity meshcontrols config=MCBM_CFG_BATCHMESH_GLB name=main_mc
*setvalue meshcontrols name=main_mc MCBM_ENTITY_SEL={comps 1 2} MCBM_MODE_CBX=0 MCBM_CRITERIA_FILE="C:/batch_criteria/crash_10mm.criteria" MCBM_PARAMS_FILE="C:/batch_criteria/crash_10mm.param"
*createmark meshcontrols 1 $main_mc_name
*batchmesh_mc 1 comps 1 0

BatchMesh the components Main_Body, Medium and Detailed, using a first order mixed mesh, keeping any adjacent existing elements.

Mesh component Main_Body with criteria file C:/batch_criteria/crash_10mm.criteria and parameters file C:/batch_criteria/crash_10mm.param.

Mesh component Medium with element size 7.0, scaling the criteria and parameters from C:/batch_criteria/crash_5mm.criteria and C:/batch_criteria/crash_5mm.param.
