In order to create a surface model with failing supports close to reality, an option called "Failure if contact perpendicular to surfaces failed" is available in RFEM 5 for contact solids under "Contact Parallel to Surfaces".

The number of degrees of freedom in a node is no longer a global calculation parameter in RFEM (6 degrees of freedom for each mesh node in 3D models, 7 degrees of freedom for the warping torsion analysis). Thus, each node is generally considered with a different number of degrees of freedom, which leads to a variable number of equations in the calculation.
This modification speeds up the calculation, especially for models where a significant reduction of the system could be achieved (e.g. trusses and membrane structures).
- Is it possible to design a spherically curved glass pane in RF‑GLASS?
- I would like to design a glass pane with temperature loads. In this case, a message appears saying that the load case includes the "temperature" surface loads types that are not transferred to the created temporary model. How can I consider the temperature loads?
- Are there any programs or add-on modules specially developed for glass structures?
- Is it possible to design insulating glass using the RF-GLASS add-on module?
- Does the activation of the partial safety factor GammaM have an effect on the calculation in RF‑GLASS?
- Is it possible to display the loads of the secondary seal of an insulating glass pane?
- When calculating a glass pane with RFEM, no stresses are displayed. Is there an error?
- Where can I find the details of a layer composition in the RF‑GLASS add-on module?
- In the calculation parameters of a load case or load combination, it is possible to activate various stiffness factors. What exactly is behind this?
- When calculating a curved surface in RF‑GLASS, I get a message saying that the surface has more than 4 boundary lines and thus no layered FE mesh can be used. How can I avoid this message?
