FEA Software RFEM | Calculation
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.

Depending on stiffness, mass, and damping, structures react differently to wind action.
- Why do I get the error message 10203 for a result beam when performing design with RF‑CONCRETE Members?
- I have a model of a timber building, which I have transferred from Scia Engineer and adapted it into the RFEM program. The models should be the same; however, it can only be calculated in Scia Engineer while RFEM reports singularity. How do I edit the model to analyze it in RFEM?
