First Steps with RFEM
Structures are naturally three-dimensional. However, because in the past, it was not possible to easily perform calculations on three-dimensional models, the structures were simplified and broken down into planar subsystems. With the increasing performance of computers and related software, it is often possible to do without these simplifications.
Digital trends, such as Building Information Modeling (BIM) or new options for creating realistic visualized models, reinforce this trend. But do 3D models really have an advantage or are we just following a trend? The following presents some arguments for working in 3D models.

The direct interface with Revit allows you to update the Revit model according to the changes you have made in RFEM or RSTAB. Depending on the modification, the Revit objects may have to be regenerated (deleting the object and subsequent regeneration). The regeneration is performed on the basis of the RFEM/RSTAB model.
If you want to avoid this regeneration, activate the option "Update only materials, thicknesses, and sections." In this case, only the properties of the objects will be adjusted. Changes different from those in material, surface thickness, and section are, however, not considered in this case.
Frequently Asked Questions (FAQ)
- I have defined a wind profile for RWIND Simulation up to a height of 100 m. Is the wind profile dependent on the size of the wind tunnel?
- As part of my bachelor thesis, I would like to integrate the RSTAB printout report into LaTeX. There, you can completely integrate a PDF document as shown in the viewer. This also works with any PDF document, but not with the printout report created by RSTAB. What could be the reason?
- How can I set the deformation coefficient kdef in the program?
- Does the program use different values of modulus of elasticity for different temperatures? How to activate it?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- I am using COM interface and Grasshopper for the calculation of complicated structures. For this task I need to create NURBS lines. Could you explain how NURBS should be set? For example what kind of data should be provided for Knots?
- I would like to move some elements. When moving, my members are deleted, what is the reason?
- How do I activate the modeling of pipelines?
- How is the load distributed to the members in the angular axis method if members are excluded from the load application?
- How can I delete the RWIND Simulation results in an RFEM or RSTAB model?
