CNTITF

Subcase Information Entry Used to activate parameters for contact (S2S and N2S) interference for this subcase.

The interference can only be applied in a root subcase of an analysis. When a contact is re-activated by MODCHG, contact interference is automatically applied (penetration is resolved linearly within the re-activated subcase). This entry is supported with nonlinear static and nonlinear transient analysis types for both small and large displacement cases.

Comments

  1. Contact interference is automatically switched to ON, if a CNTITF card is not defined in analysis. In this case, penetration is resolved in this contact linearly against subcase time in the root subcase.
