You can adjust a scale factor for the penalty stiffness applied to
surface-to-surface contact interactions when solving nonlinear studies.
The default value for the contact penalty
stiffness factor is 1.0, which yields the most accurate solution. To obtain an
approximate solution and assess design iterations faster, you can specify a value lower
than 1.0.
You can set the study-level scale factor for the penalty
stiffness in the Nonlinear- Static dialog box.
