RFEM - Structural FEA Software for Professionals
Structural Analysis & Engineering Software
The finite element analysis program RFEM is a powerful software for quick and easy modeling, structural analysis and design of 2D and 3D models consisting of member, plate, wall, folded plate, shell, solid, and contact elements.
Due to the modular software concept, you can connect the main program RFEM with the corresponding add‑on modules in order to meet your individual requirements.
Customizable GUI for Individual Adjustment
A model is created in the graphical user interface characteristic for CAD programs, using tables, or in combination of both ways. Extensive context menus facilitate data input. Since the structural model is photorealistically visualised, you can directly check the data entered.
A structure is created in the graphical user interface typical for CAD programs or by using tables. Right-clicking on graphical or navigator objects activates the shortcut menu, which facilitates creating or editing such objects. The user interface is operated intuitively. Therefore the model and loading objects can be created in a minimal amount of time.
It is possible to operate the program in the following languages: English, German, Chinese, Czech, Dutch, French, Italian, Polish, Portuguese, Russian, and Spanish.
The user‑interface design of RFEM/RSTAB can be customized.There are nine different styles of graphical user interface to choose from, for example: Office 2007 Blue, Silver, Aqua, or Black.
Program configuration menus and toolbars can be freely customized. It's possible to setup an arrangement of frequently used functions and tools for quick access. Default settings of the program can be restored at the click of a button. Tables, navigators, and toolbars can also be freely moved and docked.
The Configuration Manager provides the opportunity to define custom graphic display properties and toolbars, which can be saved and accessed later.
The photorealistic visualization of a model in 3D rendering provides a direct check of the input data. Display colors can be freely adjusted and saved separately for the screen and printout.
It is possible to assign different colors to various objects of a structure in order to make the rendering display of the structure more clearly arranged.
The following categories are available: Materials, Cross‑Sections, Member Types, Member Hinges, Surface Types - Geometry, Surface Types - Stiffness, Surface Thickness, Solid Types, Surface Sides, and User‑Defined Visibilities and Effective Length Factors.
It is possible to specifically display or hide various objects such as nodes, members, supports, and others. The model can be dimensioned by using lines, arcs, inclinations, or height elevations. Freely created guidelines, sections, and comments facilitate the input and evaluation. You can also display or hide guide objects individually.
A global dialog box manages the units of input data, loads, and results in RFEM/RSTAB as well as in all add‑on modules.
It is possible to save the settings and import it again later. That way you can use different sections in steel and reinforced concrete structures, for example.

Frequently Asked Questions (FAQ)
- For a tapered member, I get the error message "Invalid (incompatible) arrangement ...". What can I do?
- I have defined a wind profile for RWIND Simulation up to a height of 100 m. Is the wind profile dependent on the size of the wind tunnel?
- As part of my bachelor thesis, I would like to integrate the RSTAB printout report into LaTeX. There, you can completely integrate a PDF document as shown in the viewer. This also works with any PDF document, but not with the printout report created by RSTAB. What could be the reason?
- Does the program use different values of modulus of elasticity for different temperatures? How to activate it?
- How can I set the deformation coefficient kdef in the program?
- I would like to design an aluminum or lightweight structure. Is it possible to use RFEM or RSTAB for this?
- I would like to move some elements. When moving, my members are deleted, what is the reason?
- I am using COM interface and Grasshopper for the calculation of complicated structures. For this task I need to create NURBS lines. Could you explain how NURBS should be set? For example what kind of data should be provided for Knots?
- How is the load distributed to the members in the angular axis method if members are excluded from the load application?
- How do I activate the modeling of pipelines?
