Hallo Mario.
Eine Problematik, die es schon länger gibt ...
Hier der Artikel aus der (englischen) Knowledge-Base:
Symptom
When running an analysis with shell or mixed mesh, you get Material is not defined for one or more shells error message, and the analysis stops. In the Shells branch of the AnalysisManager, all the shell groups have a green check mark, showing that a material has been assigned..
Cause
The problem comes from a mismatch between the current geometry and the data in your study.
Solution
Update all components. Right click on the study name and select Update all Components
Edit each and every shell group and simply validate the definition (just click on the green check mark). Make sure that all the surfaces are indeed selected in the definition.
Update all components again. Right click on the study name and select Update all Components
Remesh and rerun.
Gutes Gelingen
