The new generation of 3D FEA software is used for the structural analysis of members, surfaces, and solids.

The Steel Design add-on performs the ultimate and serviceability limit state design checks of steel members according to various standards.

The Steel Joints add-on for RFEM allows you to analyze steel connections using an FE model. The FE model is generated automatically in the background and can be controlled via the simple and familiar input of components.

The Structure Stability add-on performs stability analysis of structures. It determines critical load factors and the corresponding stability modes.

The Stress-Strain Analysis add-on performs general stress analysis by calculating the existing stresses and comparing them with the limit stresses.

The two-part Optimization & Costs / CO2 Emission Estimation add-on finds suitable parameters for parameterized models and blocks via the artificial intelligence (AI) technique of particle swarm optimization (PSO) for compliance with common optimization criteria. Furthermore, this add-on estimates the model costs or CO2 emissions by specifying unit costs or emissions per material definition for the structural model.
