Different Stresses in Static Analysis and Stress-Strain Analysis

Why are the stresses of the structural analysis different from those calculated with the Stress-Strain Analysis add-on?


Answer:

The most likely cause of the different results is that you have probably not set the same smoothing of the surface internal forces.

This can be set separately in RFEM 6 and in the add-on.

If the smoothing is the same in both settings, the stresses are also the same.
