FEA Software RFEM | Calculation

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.

  1. Individual Setting of Calculation Parameters

    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.

  2. Incremental Load Application

    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.

  3. Multi-Core Processor and 64-Bit Technology

    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.
