Nonlinear Material Behavior
The Nonlinear Material Behavior add-on allows you to consider material nonlinearities in RFEM. If you use nonlinear material models in RFEM, the program always performs an iterative calculation. Depending on the material model, it defines a different relation between the stresses and strains. The stiffness of the finite elements is adjusted again and again in the course of the iterations until the stress-strain relation is met.
Construction Stages
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Lateral-Torsional Buckling with Warping Torsion
The Torsional Warping (7 DOF) add-on allows you to consider cross-section warping as an additional degree of freedom.
Geotechnical Analysis
In RFEM, the Geotechnical Analysis add-on uses the properties from soil samples to determine a soil body to be analyzed.
Response Spectrum Analysis
The Response Spectrum Analysis add-on performs seismic analysis using multi-modal response spectrum analysis. The spectra required for this can be created in compliance with the standards or can be user-defined. The equivalent static forces are generated from them. The add-on includes an extensive library of accelerograms from seismic zones that can be used to generate the response spectra.
Time-Dependent Analysis (TDA)
The Time-Dependent Analysis (TDA) add-on allows you to consider the time-dependent material behavior of members and surfaces. The long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure.
Optimization of Model Parameters
The add-on uses particle swarm optimization (PSO) to determine optimal parameters for parameterized models based on weight, cost, or CO2 emissions.

Definition of Multilayer Surfaces Such as Cross-Laminated Timber (CLT)
The Multilayer Surfaces add-on allows you to define multilayer surface structures. The calculation can be carried out with or without the shear coupling.
