*topography_reanalysis

Syntax

*topography_reanalysis grid_filename sh_filename autobead bead_threshold layers isosurface mode density_threshold

Type

HyperMesh Tcl Modify Command

Description

Extract the final geometry from OptiStruct topology, topography and shape optimization results and inherit the boundary conditions for reanalysis.

Inputs

grid_filename

The full name and path to the OptiStruct .grid results file generated from the optimization.

sh_filename

The full name and path to the OptiStruct .sh results file generated from the optimization.

autobead

Flag that determines whether to create beads. Valid values are:

0 - Do not create beads.

1 - Create beads.

bead_threshold

The threshold value for bead creation (0 <= bead threshold <= 1).

isosurface

Flag that determines whether to create isosurfaces. Valid values are:

0 - Do not create isosurfaces.

1 - Create isosurfaces.

mode

Iso-surface mode indicating how to process non-design elements. Valid values are:

0 - Keep all non-design elements with a half layer around.

1 - Split only intersected non-design elements.

2 - Split overlapping non-design elements with a half layer around.

3 - Split overlapping non-design elements.

density_threshold

Threshold value for topology optimization (0 ≤ density threshold ≤ 1).

Example

Execute OSSmooth on the C:/test/os1.grid and C:/test/os.sh files, loading the geometry back to HyperMesh, creating 1 layer autobead with 0.3 bead threshold, splitting all quads on non-design/design interface, with a density threshold of 0.3:

*topography_reanalysis "C:/test/os1.grid" "C:/test/os1.sh" 1 0.3 1 1 3 0.3

Errors

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