DEFINITION
MGWSTR specifies the element density weight to be associated with the elemental strain rate values when an object is being meshed using AMG.
REMARKS
MGWSTR is one of several keywords used to control the mesh density during AMG mesh generation. The values from all the mesh density keywords are combined during the mesh generation process to create a mesh density distribution within the geometric boundary.
The keywords MGWCUV, MGWSTN, MGWSTR, MGWTMP, and MGWUSR specify relative mesh density weights to be assigned to the associated keyword parameter (curvature, strain, strain rate, temperature, and user defined area).
When an object is deformed, strain rate is recorded at the element center. When a remeshing is performed, the value of WtSrate specifies the emphasis to be placed on the elemental strain rate interpolation error as a parameter for determining mesh density during a remeshing.
If WtSrate > 0, the mesh density will be allocated so that areas with the greatest strain rate gradients will receive a higher mesh density than areas with lower strain rate gradients.
If WtSrate < 0, elemental strain will not be used to determine the mesh density.
MGWSTR should only be used when a mesh with previous elemental strain values is being remeshed.
Applicable object types: Rigid, Elastic, Plastic, Elastoplastic, and Porous.
