Q: What does the message "*** WARNING: xxx Sig. Figures Lost At *X.XXX" mean?
REV 7.00

A: This is an indication of problems with the model, related to relative stiffness at the referenced node. By looking at all the elements that frame into this node, it should be apparent which element is causing the problem. Significant figures lost up to 4 or 5 are typically ignored, as long the overall structural results look good. Somewhere beyond 6 significant figures lost, the stiffness matrix is declared singular.
