When performing an analysis in RF‑STABILITY, I get the message "The stiffness matrix is singular! The structure is unstable. Instability found in FE mesh node XY." How can I find this FE mesh node?


In RFEM, it is possible to search for FE mesh nodes by using the menu "Edit"→ "Find via Number." An existing FE mesh is required, of course.
