Description

With this command activated smoothed pressure values are calculated. The smoothed pressure replaces the element integration point pressure in the material damage evolution calculations. The purpose is to avoid non-physical damage growth due to pressure locking. Pressure locking is primarily a problem for severely distorted elements.
