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.

Set identification number of a CNTITF Bulk Data Entry.


  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.
