Warning message regarding singularities...HELP!!!

[ideasta]

I am trying to solve a model, nut I get 101 warnings, some of them say that there is a # singularities, some of them say that the orrective stiffnesses have been added...
Any ideas as to what this can be related to?

rigid body motion i.e. your model is floating in space no sufficient constraints.
