Edge-to-Edge Interface (/INTER/TYPE11)

Interface TYPE11 is used to simulate impact between lines for 1D mesh, or edges in shell and solid meshes.

In association with interface TYPE7, interface TYPE11 solves the locking cases and uses the same penalty formulation and search algorithm as interface TYPE7.

Interface TYPE 11 uses complicated mathematical algorithms; therefore, it is strongly advised to use it only when necessary. A huge interface TYPE11 can slow down the computation.
