*hm_batchmesh2

The following mesh and geometry cleanup strings have an effect only if elem_size is specified and has a valid value.

params_generate_mode=<mode>

Defines the auto-generate mode. Valid values are:

generic - Generic, universal parameters are created (default)

scale - The given criteria_file and param_file files are scaled to elem_size.

midmesh - Parameters specialized for shell models obtained by mid-surface extraction are created

shell - Parameters specialized for shell models are created

solid - Parameters specialized for solid models are created

min_elem_size=<size>

The minimum element size, used for quality criteria auto-generation. Default is 0.3*elem_size.

max_elem_size=<size>

The maximum element size, used for quality criteria auto-generation. Default is 1.75*elem_size.

elem_type=<type>

0 - Trias

1 - Quads

2 - Mixed (default)

elem_order=<order>

1 - First (default)

2 - Second

elem_feature_angle=<angle>

The minimum angle, in degrees, between elements for feature element edges. Default 25.

no_geomcleanup=<mode>

0 - Geometry cleanup is applied (default)

1 - Geometry cleanup is not applied

no_remove_holes=<mode>

0 - Small hole removal during geometry cleanup is enabled (default). The default diameter for removal is max(0.4*elem_size, 0.8*min_elem_size).

1 - Small hole removal during geometry cleanup is disabled.

no_seed_holes=<mode>

0 - Holes seeding with fixed points during geometry cleanup is enabled (default).

1 - Holes seeding with fixed points during geometry cleanup is disabled.

no_washer=<mode>

0 - Washer creation is enabled (default).

1 - Washer creation is disabled.

no_node_move_across_edges=<mode>

0 - Nodes are allowed to be moved across non-feature geometry edges (default).

1 - Nodes are not allowed to move off geometry edges.

no_advkeepfeatures=<mode>

0 - Advanced feature capturing is enabled (default).

1 - Advanced feature capturing is disabled.

breakconnectivity=<mode>

0 - Mesh connectivity is maintained with parts of the model not selected (default).

1 - Mesh connectivity is broken with parts of the model not selected.

keep_plotelems=<mode>

0 - Plot elements are deleted. This is how standalone Batchmesher behaves.

1 - Plot elements are not deleted (default).

batchtempfilesmode=<mode>

0 - Temp files are not created (default). This improves performance but internal rollback of failed steps is not possible.

1 - Temp files are created in a temp directory and removed after command completion. This decreases performance but allows internal rollback of failed steps.

2 - Temp files are created in a temp directory and kept after command completion. This decreases performance but allows internal rollback of failed steps.

save_model=<mode>

0 - A backup model is not saved and reject of the command is not possible.

1 - A backup model is saved with an auto-generated name with the prefix batchmeshbackup, and reject of the command is possible (default).

number_of_strings

Integer indicating the size (number of strings) in the string array created using *createstringarray.

criteria_file

The full path and file name of the criteria file. If the criteria are set by a preceding command, "dummy" can be used.

This is ignored if params_generate_mode is set in the strings input.

param_file

The full path and file name of the parameter file. If the params are set by a preceding command, "dummy" can be used.

This is ignored if params_generate_mode is set in the strings input.

BatchMesh surfaces 36 and 79 using the criteria file C:/crit/10mm.criteria and parameters file C:/crit/10mm.param, with all other default parameters:

*createmark surfs 1 36 79
*hm_batchmesh2 surfs 1 1 0 "C:/crit/10mm.criteria" "C:/crit/10mm.param"

BatchMesh surfaces 36 and 79 using the criteria file C:/crit/10mm.criteria and parameters file C:/crit/10mm.param, breaking mesh connectivity, with all other default parameters:

*createmark surfs 1 36 79
*createstringarray 1 "breakconnectivity = 1"
*hm_batchmesh2 surfs 1 1 0 "C:/crit/10mm.criteria" "C:/crit/10mm.param"

BatchMesh surfaces 36 and 79 with element size 8.0 and minimum size 3.75. Use auto-generated shell criteria and parameters. Allow internal reject steps via temp files:

*createmark surfs 1 36 79
*createstringarray 2 "elem_size = 8 min_elem_size = 3.75 params_generate_mode = shell" "batchtempfilesmode = 1"
*hm_batchmesh2 surfs 1 1 2 "dummy" "dummy"

BatchMesh surfaces 36 and 79 with element size 7.0, using scaling of the criteria C:/crit/10mm.criteria and parameters file C:/crit/10mm.param. Do not output temporary files to allow internal reject:

*createmark surfs 1  36 79
*createstringarray 2 "elem_size = 7.0 params_generate_mode = scale" "batchtempfilesmode = 0"
*hm_batchmesh2 surfs 1 1 2 "C:/crit/10mm.criteria" "C:/crit/10mm.param"

Incorrect usage results in a Tcl error. To detect errors, you can use the catch command:

if { [ catch {command_name...} ] } {
   # Handle error
}
