When Caesar informs the user that the "Stiffness Matrix has been detected as being almost numerically singular", what does it mean?
(residuals cannot converge?)
My model contains:
- 2 anchors (one at each end)
- no CNodes
- no structural stuff
I am reluctant to change the "Decomposition_Singularity_Tolerance" yet. Is there a quick way to locate any "rigid body motion"?
Thanks
