Error in 3D contact code. This is usually related to excessive
iterative displacements, which cause difficulties in finding
the correct new position of nodes in contact. Possible remedies
are:
- use the iterative penetration checking procedure;
- reduce the load incrementation;
- define the maximum change in the incremental displacement to
be equal to e.g. a characteristic element length;
- for incompressible materials, only use the tensile stresses
in the geometric stiffness matrix.
If the problem remains, please consult an MSC Software analyst.
