Nonlinear Buckling Analysis

3D Finite Element Analysis and Design

Structural engineering FEA software RFEM is the basis of a modular software system. RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.

Stability Analysis According to Eigenvalue Calculation Method

RF-STABILITY determines buckling shapes and critical load factors of the model using the Eigenvalue Method. Therefore, it is especially suitable for linear and nonlinear analysis of stability behaviour.

Generation of Equivalent Geometric Imperfections and Pre-Deformed Initial Models

RF-IMP creates equivalent geometric imperfections (equivalent lateral loads) or a pre‑deformed initial model.

Application of Nonlinear Material Laws

RF-MAT NL allows you to apply the nonlinear material laws in RFEM.
