Finite Element Analysis (FEA) Solutions
Recommended Products for Finite Element Analysis (FEA)
Consideration of Construction Stages
The Construction Stages Analysis (CSA) add-on allows for considering the construction process of structures (member, surface, and solid structures) in RFEM.
Time-Dependent Analysis (TDA)
The Time-Dependent Analysis (TDA) add-on allows you to consider the time-dependent material behavior of members. The long-term effects, such as creep, shrinkage, and aging, can influence the distribution of internal forces, depending on the structure.
Form-Finding of Membrane Structures
The Form-Finding add-on finds the optimal shape of members subjected to axial forces and tension-loaded surface models. The shape is determined by the equilibrium between the member axial force or the membrane stress and the existing boundary conditions.
Geotechnical Analysis Using FEM
In RFEM, the Geotechnical Analysis add-on uses properties from soil samples to determine the soil body to be analyzed. The accurate determination of soil conditions significantly affects the quality of the structural analysis of buildings.
Seismic 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 History Analysis
The Time History Analysis add-on allows you to perform dynamic structural analysis of external excitation. You can define various excitation functions in tables or as a function of time. The time history analysis is performed using the modal analysis or the linear implicit Newmark analysis.
Generation, Analysis, and Evaluation of Building Models
The Building Model add-on for RFEM allows you to define and manipulate a building using stories. The stories can be adjusted in many ways afterwards. The information about stories and the entire model (center of gravity) is displayed in tables and graphics.
Model Optimization Using Artificial Intelligence (AI)
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.
Definition of Multilayer Surfaces, such as Laminate Surfaces or 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.
Masonry Design According to FEM
The Masonry Design add-on for RFEM allows you to design masonry using the finite element method. It was developed as part of the research project titled DDMaS – Digitizing the Design of Masonry Structures. The material model represents the nonlinear behavior of the brick-mortar combination in the form of macro-modeling.

Pushover Analysis
Earthquakes may have a significant impact on the deformation behavior of buildings. A pushover analysis allows you to analyze the deformation behavior of buildings and compare them with seismic actions. Using the Pushover Analysis add-on, you can analyze the seismic actions on a particular building, and thus assess whether the building can withstand the earthquake.

You can use the "Dashpot" member type to define a damping coefficient, a spring constant, and a mass. This type of member expands the possibilities within the time history analysis.
With regard to viscoelasticity, the member type "Dashpot" is similar to the Kelvin-Voigt model, which consists of the damping element and an elastic spring (both connected in parallel).
For rigid links, it is possible to define line hinges. This allows for semi-rigid coupling of different elements, for example.
