RFEM - Structural FEA Software for Professionals
Structural Analysis & Engineering Software
The finite element analysis program RFEM is a powerful software for quick and easy modeling, structural analysis and design of 2D and 3D models consisting of member, plate, wall, folded plate, shell, solid, and contact elements.
Due to the modular software concept, you can connect the main program RFEM with the corresponding add‑on modules in order to meet your individual requirements.
Linear and Nonlinear Structural Analysis
The model is calculated linearly using linear static analysis or nonlinearly with large deformation analysis. In order to determine internal forces, results can be superimposed in combinations.
All member types can be calculated according to the linear static, second-order or large deformation analysis. The selection option is available for load cases and load combinations. Further calculation parameters are individually adjustable for load cases, load and result combinations. Thus, high flexibility regarding the calculation method and detailed specifications is ensured.
Loads can be applied incrementally. The increment option is especially useful for calculations according to the large deformation analysis. For members, you can consider shear deformations and apply internal forces to a deformed or undeformed structural system. In addition, RFEM allows you to perform post‑critical analysis.
The equation solver includes an optimized FE mesh generator and supports the latest multi-core processor and 64-bit technology. Therefore, you can perform parallel calculations of linear load cases and combinations by using several processors without additional random access memory (RAM): The stiffness matrix has to be created only once. The 64-bit technology and the enhanced RAM options allow for calculation of complex structural systems using the fast and direct equation solver.
Deformation development is displayed in a diagram during the calculation. In this way, you can easily evaluate the convergence behavior.

Frequently Asked Questions (FAQ)
- Is it possible to display more values for the stress distribution over the layers in RF-LAMINATE?
- How is the position of the additional reinforcement considered in RF-CONCRETE Surfaces when determining hc, ef?
- 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?
- For a tapered member, I get the error message "Invalid (incompatible) arrangement ...". What can I do?
- 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?
- 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?
- 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?
- How can I set the deformation coefficient kdef in the program?
- I am using the COM interface and Grasshopper for the calculation of complex structures. For this task, I need to create NURBS lines. Could you explain how to set NURBS? For example what kind of data should be provided for Knots?
