Solutions for Finite Element Analysis (FEA)
Recommended Products for Finite Element Analysis (FEA)
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.
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 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.
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.
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 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.

In the "Import Support Reaction" load wizard, the "Free Loads" object connection type is available in addition to the "Manual" ones. This option saves you the task of manually assigning the support reactions to specific nodes and lines. The support forces of the connected model are applied as free loads in this option.
![Feature 002852 | Spline surface with minimum curvature](/en/webimage/051665/3996349/2.png?mw=512&hash=495637ed9f78ff76e0ac09e73585e9001cb15ebb)
You can use the "spline with minimum curvature" surface geometry type to generate curved surfaces on the basis of the control nodes in the middle of the surface.
This can be used to model terrain surfaces, for example.
![Feature 002853 | Design check details about mesh node selection in graphics](/en/webimage/051681/3998147/1.png?mw=512&hash=9d7f6c198b6d4ae6ee8f2fa8bca75f85579e14c9)
In the result diagrams in the surface point, you can simply select the mesh nodes in the graphic to display the detailed results at this point.
