When analyzing in RF-STABILITY, I get the message 'The Stiffness Matrix is Singular!' The structure is unstable in the FE mesh node XY. How to find this FE mesh node?

Answer

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