Hello dear Dlubal team,
I am currently performing calculations on a volume model made of wood. When reviewing the results of the principal stresses in these volume bodies, some of the stress distributions relative to the local coordinate systems appeared different than expected. During my research in the manual, I could not find any detailed information about the reference coordinate system for the principal stresses in volume bodies. When I asked Dlubal's own AI, "What is the reference coordinate system for the results of the principal stresses in volume bodies?" I received this answer: "The results of the principal stresses in volume bodies in RFEM 6 are always displayed in the global coordinate system. It is not possible to switch to a user-defined coordinate system for these results. The stresses on the boundary surfaces of the volume bodies are color-coded according to the smoothing settings defined in the program. If a more detailed analysis inside the volume is desired, a clipping plane can be used.
If output in a local coordinate system is required, local results on members or surfaces are recommended, as display in the local system is possible here.
Would you like further details or specific settings to be explained when displaying the stresses in volume bodies?"
However, in the sources listed under the AI answer, there is no indication of the reference coordinate system for results in volume bodies. Now I am not sure whether this answer might just be an incorrect combination of the respective sources.
I would appreciate a validation of the answer or a reference to the appropriate section in the manual.
Best regards
Baustudi
