*remesh_optistruct

Remeshes the current model with FE type definitions maintained, used to improve the mesh quality in OptiStruct free shape, shape or topography optimization.

Syntax

*remesh_optistruct string_array number_of_strings

Type

HyperMesh Tcl Modify Command

Description

Remeshes 2D elements at intersection locations. Only elements belonging to different components are taken as counterparts for the intersection calculation. Moreover, elements sharing a node are not counterparts for the intersection calculation.

Inputs

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.

Each argument can be either comma or space separated. There are at most six string parameters, depending on the user inputs required.

Valid strings are:

"fgrd: filepath_grid": This sting is optional, indicating the .grid file to be applied to update the shape of the model.; filepath_grid; The full name and path to the OptiStruct .grid results file generated from the optimization.
"fsh: filepath_sh": This sting is optional, indicating the .sh file to be used in remeshing.; filepath_sh; The full name and path to the OptiStruct .sh results file generated from the optimization.
"fdesvar: filepath_desvar": This sting is optional, indicating the .desvar file to be used in remeshing.; filepath_desvar; The full name and path to the OptiStruct .desvar file generated from the optimization.
"fhist: filepath_hist": This sting is optional, indicating the .hist file to be used in remeshing.; filepath_hist; The full name and path to the OptiStruct .hist file generated from the optimization.
"skipgs: id1 id2 ...": This string is only required when there are grids which will be unchanged during remeshing. Note that grids in a SET named as '^skipgs' will be excluded, as well.; id1 id2 ...; ID list of grid sets which will keep unchanged during remeshing.
"skiges: id1 id2 ...": This string is only required when there are elements which will be unchanged during remeshing. Note that grids in a SET named as '^skipes' will be excluded, as well.; id1 id2 ...; ID list of element sets which will keep unchanged during remeshing.

number_of_strings

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

Example

To executes the function on the current model, taking the optimized grid coordinates from the file C:/test/torquearm.grid, and performing remeshing with grids in SET number 2 fixed:

*createstringarray 2 "fgrd: C:/test/ torquearm.grid" "skipgs: 2"
*remesh_optistruct 1 2

Errors

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

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