Penalty Stiffness Control for Contact

You can specify a scale factor for the penalty stiffness for contact that is used in linear static studies.

SOLIDWORKS Simulation uses a default scale factor of 1.0 for the penalty stiffness to reach an accurate solution for linear static studies with contact interactions. However, you can select a lower scale factor to obtain an approximate solution faster to assess design iterations and the overall behavior of a model.

You can set the study-level scale factor for the penalty stiffness in the Study Properties dialog box. For global-level settings, select Simulation > Options > Default Options > Interactions.
