  1. CONTX11 is only applied in Geometric Nonlinear Analysis Subcases which are defined by ANALYSIS = EXPDYN. It is ignored for all other subcases.
  2. The property of CONTX11(PID) only can be defined by PCONT and its extended card PCNTX11.
  3. CONTX11 defines contact interface TYPE11, it describes the edge to edge or line to line interface. This interface simulates impact between lines, a line can be a beam or truss element or a shell edge or spring elements. The interface properties are:
    • impacts occur between a main and a secondary line
    • a secondary line can impact on one or more main lines
    • a line can belong to the main and the secondary side. This allows self impact
    • this interface can be used in addition to the interface TYPE7 PCNTX7 to solve the edge to edge limitation of interface TYPE7
  4. The secondary line entity SLID and main line set entity MLID must be defined via LINE:
    • a set of edges or lines of 1D, 2D or 3D elements
    • a set of elements (bars, beams, springs or shells), defined using SET(ELEM, ...) command
  5. This card is represented as a group in HyperMesh.
