HyperMesh Ext API Function

Description

This structure contains information that is used by the HM_ExtAPI::GenerateMesh() function to set meshing parameters in interactive and batch meshing modes.

The structure information is declared in hm_extapi.h.

The members are: size, element_size, element_order, mesh_type, mesh_option_flags, param_file_path, criteria_file_path, BM_folder_path, MA_file_path, num_local_batchparamsets, local_batchparamsets

Inputs

size: Specifies the length, in bytes, of the structure. Use sizeof(HM_GenerateMeshParamStruct) for this member. This is used to distinguish the current version of HM_GenerateMeshParamStruct from possible future extended versions with additional members.
element_size: Specifies the mesh size. This member is ignored if the member param_file_path is not NULL.
element_order: Specifies the order (degree) of elements to generate. This member is ignored if the member param_file_path is not NULL.; This member can have one of following values:; HM_ELEMORDER_DEFAULT - First order elements are generated.; HM_ELEMORDER_FIRST - First order elements are generated.; HM_ELEMORDER_SECOND - Second order elements are generated.
mesh_type: Specifies the type of elements to generate. This member is ignored if the member param_file_path is not NULL.; This member can have one of following values:; HM_MESHTYPE_DEFAULT - Mixed mesh: triangular and quadrilateral elements are generated.; HM_MESHTYPE_TRIA - Tria mesh: only triangular elements are generated.; HM_MESHTYPE_QUAD - Quad mesh: mostly quadrilateral elements are generated.; HM_MESHTYPE_MIXED - Mixed mesh: triangular and quadrilateral elements are generated.
mesh_option_flags: A set of bit flags that can be used to specify additional mesh generation options. This member is ignored if the member param_file_path is not NULL.; The value of this member can be a combination of the following flags:; HM_MESHOPTS_DEFAULT - Default parameters are used for mesh generation.; HM_MESHOPTS_EDGELINK - Forces edges in quadrilateral regions to have equal number of nodes.; HM_MESHOPTS_MESHALIGN - Improves global alignment of elements in generated mesh.; HM_MESHOPTS_FORCE_ELEMSIZE - Enforces specified element size and prevents smooth element size transitions between regions meshed previously with different element sizes.
param_file_path: Name of the text file containing parameters for meshing. If this parameter is NULL then parameters specified by members element_size, element_order, mesh_type, and mesh_option_flags are used to control mesh generation.
criteria_file_path: Name of the text file containing criteria parameters for meshing.
BM_folder_path: Name of the folder where HyperMesh writes out result files.
MA_file_path: Name of the file to write out the model with realized mesh areas given as input in a call to the HM_ExtAPI::GenerateMesh() function and a mesh generated during the call. The file is written out in a format of HyperMesh model file. If this parameter is NULL then the file is not created.
num_local_batchparamsets: The number of local batch mesh parameter/criteria file sets used for individual batch meshing of specified topology faces and/or components.
local_batchparamsets: Pointer to an array of local batch mesh criteria/parameter file sets used by HM_BatchMeshParamSet for individual batch meshing of specified topology faces and/or components. The number of values in the array must not be smaller than the value specified by num_local_batchparamsets.

Errors
