Solver problem. Numerical singularity at D.O.F. 3 at one or more of the internal nodes of 40 elements. The elements have been identified in element set WarnElemSolvProbNumSing_3_0_0_0_0.
The elements in element set WarnElemFailElemInContact are part of a deformable surface that is referenced by a *CONTACT PAIR option in addition to having material properties that allow the element to fail. For elements that can fail, contact should be defined using the *CONTACT option.
