FilterSIMULIA 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. 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 ABS olute units (default) or REL ative (in terms of the
medium edge length). Default value is 4 * medium_edge_length. To disable filtering, use
0 or any negative value. Using the
FILTER_RADIUS=<value> parameter is equivalent to using the three
parameters
It is also possible to set individual filter radii. For the objective function sensitivity filtering use For filtering the sensitivities of the constraints, use and for filtering the design variables use
