Definition

Interface type 11 is used to simulate impact between lines for 1D mesh, or edges in shell and solid meshes.

In association with interface type 7, interface type 11 solves the locking cases and uses the same penalty formulation and search algorithm as interface type 7.

Interface type 11 uses complicated mathematical algorithms; therefore, it is strongly advised to use it only when necessary. A huge interface type 11 can slow down the computation.
