*hm_batchmesh2
Performs interactive BatchMeshing.
Syntax
*hm_batchmesh2 entity_type mark_id string_array number_of_strings criteria_file param_file
Type
HyperMesh Tcl Modify
Description
Performs interactive BatchMeshing.
Currently, to undo this command, call *rejectbatchmesh with no parameters. Reject is possible only if the save_model string parameter is omitted or set to 1. Undo is also not possible after any other command is called.
Inputs
- entity_type
- The entity type to perform the BatchMeshing for. Valid values are surfs and comps.
- mark_id
- The ID of the mark containing the entities to mesh. Valid values are 1 and 2.
- string_array
- The ID of the string array that contains the additional input parameters. The string array is created using the *createstringarray command. This should always be set to 1.
MESH AND GEOMETRY CLEANUP PARAMETERS ( AUTOGENERATION )
- elem_size=<size>
- The target element size.
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:
- 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
- elem_order=<order>
- 1 - First (default)
- 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)
The following geometry cleanup strings have an effect only if no_geomcleanup is 0.
- 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).
- no_seed_holes=<mode>
- 0 - Holes seeding with fixed points during geometry cleanup is enabled (default).
- no_washer=<mode>
- 0 - Washer creation is enabled (default).
- no_node_move_across_edges=<mode>
- 0 - Nodes are allowed to be moved across non-feature geometry edges (default).
- no_advkeepfeatures=<mode>
- 0 - Advanced feature capturing is enabled (default).
- breakconnectivity=<mode>
- 0 - Mesh connectivity is maintained with parts of the model not selected (default).
- keep_plotelems=<mode>
- 0 - Plot elements are deleted. This is how standalone Batchmesher behaves.
- batchtempfilesmode=<mode>
- 0 - Temp files are not created (default). This improves performance but internal rollback of failed steps is not possible.
- save_model=<mode>
- 0 - A backup model is not saved and reject of the command is not possible.
- 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.
- 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.
Examples
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"
Errors
Incorrect usage results in a Tcl error. To
detect errors, you can use the catch
command:
if { [ catch {command_name...} ] } {
# Handle error
}
