Constr Screen Panel
Use the Constr Screen panel to define the data for constraint screening.
Location: Analysis page > Optimization panel
Note: Only available in the OptiStruct solver interface.
| Option | Action |
|---|---|
| Auto Screen | Automatically screen
constraints. The screening algorithm will seek to retain the
smallest number of responses that are necessary for stable
convergence. This option is disabled by the presence of any DSCREEN definition in the input data. |
| Level 1-5 / off | Select a level of
automatic constraint screening. The automatic constraint screening has levels 1 through 5, with 1 being the least aggressive (more responses retained) and 5 being the most aggressive (fewer responses retained). Level 3 is the default. Disable automatic constraint screening (even when the checkbox is selected) by selecting OFF. |
| MASS | Enter threshold and max retained values for mass. |
| MASSFRAC | Enter threshold and max retained values for fraction of mass. |
| VOLUME | Enter threshold and max retained values for volume. |
| VOLFRAC | Enter threshold and max retained values for fraction of design volume. |
| COG | Enter threshold and max retained values for center of gravity. |
| INERTIA | Enter threshold and max retained values for moment of inertia. |
| COMP | Enter threshold and max retained values for compliance of a static subcase. |
| DISP | Enter threshold and max retained values for static displacement/mode shape. |
| FREQ | Enter threshold and max retained values for frequency of a normal mode. |
| LAMA | Enter threshold and max retained values for eigenvalue of a buckling mode. |
| STRESS | Enter threshold and max retained values for static stress of homogenous material. |
