Question

In the current program version of RFEM, the calculation no longer converges. I have already calculated the model in different RFEM versions:
RFEM 5.21.02 - Calculation converges
RFEM 5.23.02 - Calculation does not converge
RFEM 5.24.01 - Calculation does not converge


Answer:

In RFEM 5.23, changes have been made to the calculation kernel which lead to a slightly different, more "sensitive" behavior of the nonlinear supports.

In this case, it is helpful to adjust the diagrams for the nonlinear supports slightly: Instead of applying the stop directly, you could define a slightly "smoother" transition.
