Error Message in RFEM 5 for Timber Members: Isotropic Material Model Required

My RFEM 5 model includes members and surfaces/solids made of timber. I have already created the 2D/3D orthotropic material model. Now, I receive an error message saying that the material model for cross-section X must be isotropic.


Answer:

In this case, the orthotropic material model is probably assigned to both the surfaces/solids and the members. However, timber members require an isotropic material model. Therefore, it is necessary to create another timber material and assign it to the corresponding members or cross-sections.
