Debug Numerical Singularities

Use a Frequency (normal modes) analysis to verify that a model is fully constrained. All materials will need to have a density assigned for this analysis procedure. Any results with a frequency near zero are indications of an under-constrained model which will show up as NUMERICAL SINGULARITY convergence difficulties in Abaqus/Standard. Animate these modes to visualize the problem.
