Answer:
For the surface type with the "glass" stiffness, no stresses result in RFEM 5. The reason is that this stiffness type is only a placeholder for the RF‑GLASS add-on module. This means that the program requires more data for the glass pane, such as layers, nodal supports, boundary members, or load duration entries. You can enter the data in the RF‑GLASS add-on module. It is also possible to evaluate the stresses, loads, and deformations by layer here (see Image 01 and Image 02).
