Filter

SIMULIA Tosca Structure uses a filter on the objective function sensitivities, the constraint sensitivities and the design variables to gain smooth results. The filter settings can be altered to either use another filter radius or to disable the filter. 


SHAPE_FILTER_RADIUS= <positive_real_value>, [ABS|REL]
The filter radius is used to filter the objective function sensitivities, the constraint sensitivities, and the design variables. The second parameter indicates if the radius is given in ABSolute units (default) or RELative (in terms of the medium edge length). Default value is 4 * medium_edge_length. To disable filtering, use 0 or any negative value.
