In result window 2.1 "Punching Shear Design", I receive the error No. 56 "The FE mesh is not fine enough". How can I stop the mesh?

Answer

Depending on the selected type of load determination, RF-PUNCH Pro determines the punching load from the shear forces in the critical perimeter. The surface internal forces from the RFEM model are taken into account here.

If the FE mesh in the area of the punching node is not fine enough, it may lead to inaccurate results. In this case, you will receive Message No. 56.

To avoid the problem, you should perform an FE mesh refinement in the region of the punching-through node in the RFEM model. You can arrange them either directly on the node or on the connecting lines of wall ends or wall corners.

If the FE mesh refinement is fine enough, the warning message disappears automatically after a recalculation in RF-PUNCH Pro.
