Question

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?


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