Type
HyperMesh Tcl Modify Command
Description
Generates a hex mesh for the far-field, a tetra mesh for the interface clearance, and a 3D boundary-layer mesh on the body.
Inputs
- mark_id
- The ID of the mark containing the body components. Valid values are 1 and 2.
- elem_size
- The target far-field hex element size.
- interface_clearance
- Clearance value from body. The tetra mesh is generated to the clearance volume.
- front_space
- Far-field front space from body.
- rear_space
- Far-field rear space from body.
- side_space
- Far-field side space from body.
- top_space
- Far-field top space from body.
- string_array
- The ID of the string array that contains the additional meshing parameters. The string array is created using the *createstringarray command. This should always be set to 1.
- number_of_strings
- Integer indicating the size (number of strings) in the string array created using *createstringarray.
Example
To generate a wind tunnel mesh using all components for the body, a hex size of 10.0, an interface clearance of 20, a far-field size of 300 (front)/400 (rear)/200 (side)/200 (top), and specific boundary layer meshing parameters:
*createstringarray 2 "tet_bl_param: 11 0.01 1.2" "bottom_bl_param: 5 0.1 1.3"
*createmark components 1 all
*wind_tunnel_mesh 1 10.0 20.0 300 400 200 200 1 2Errors
Incorrect usage results in a Tcl error. To detect
errors, you can use the catch
command:
if { [ catch {command_name...} ] } {
# Handle error
