KB 001605 | Modeling surfaces lying on top of each other: Hazards and suggested solutions
Video
First Steps with RFEM
Description
When modeling with finite elements, you sooner or later come up with the question of how two surfaces (2D elements) lying on top of each other can be modeled. Hence, both surfaces are quite often modeled in the same plane. The possible consequences of this approach and whether there are better solutions are described below.

For relatively large or relatively small surfaces, it can happen that the automatically created result values do not fit the model: In case of large surfaces, there can be too much result values, in case of small surfaces, too few.
Material Model Orthotropic Masonry 2D
The material model Orthotropic Masonry 2D is an elastoplastic model that additionally allows softening of the material, which can be different in the local x- and y-direction of a surface. The material model is suitable for (unreinforced) masonry walls with in-plane loads.
- How are the signs to be interpreted for the release results of the line release and line hinges?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- How do I display the nodal displacements graphically?
- Are silos/tanks possible to export from RFEM into Revit?
- Is it possible to also have RFEM output the area of each finite element along with its location?
- Are the models and presentations from Info Day 2020 freely available, and can you send them to me?
- Are the models and presentations from Info Day 2017 freely available, and can you send them to me?
- When creating a material, there are no nonlinear material models available for surfaces or solids. Why?

When trying to import a model from AutoCAD into RFEM, I am getting the error message "3DSOLID or REGION entity detected. Those entities are written in binary format, so import is not possible."
What does this mean?
