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