Finite Element Method (FEM)

FEM is a method of analysis for the tasks in the scientific and technical field. It enables you to calculate complex problems that would otherwise not be able to be solved or solved very inefficiently by other means. It is thus one of the most important methods in structural engineering.

The term FEM describes a numerical method for solving differential equations. Therefore, various physical disciplines rely on these calculations. To analyze a structural component, it is first decomposed into a large number of finite elements. Due to their simple geometry, these elements can then be easily calculated using the known shape functions. This decomposition into finite elements eventually gave the name to this method: the "Finite Element Method".

Nowadays, FEM is a standard method in structural engineering for the computer-aided calculation of beam and surface structures.

3D FEA Software for Structural and Dynamic Analysis and Design

The structural analysis program RFEM 6 is characterized by its user-friendly application of the finite element method in structural engineering. Sophisticated input technology allows you to model simple and complex structures completely and intuitively after a short training period. RFEM does the calculations for you. It performs structural and dynamic analysis of all 3D structures with absolute reliability.

RFEM is the basis of a modular program family. The main program RFEM 6 is used to define structures, materials, and loads of planar and spatial structural systems consisting of plates, walls, shells, and members.

Furthermore, RFEM also calculates the internal forces and support forces. Does your project consist of different elements and materials? This is not a problem, because combined structural systems are just as possible with RFEM as handling solid and contact elements.

For a standard-compliant design of components made of different materials, you need the corresponding add-ons and additional modules. You can compile the programs according to your needs. In the end, you get exactly the software you need for your daily work.

Add-ons and Add-on Modules for RFEM

Would you like a little more RFEM? As already mentioned, we have numerous add-ons and additional modules for the main program RFEM. So if you need to design different materials, such as reinforced and prestressed concrete, steel, aluminum, timber, or glass, we provide you with a large number of powerful add-ons and additional modules.

These extensions offer a range of possibilities. Use the add-ons and add-on modules for RFEM to perform nonlinear calculations, stability and dynamic analyses, joint design checks, and form-finding processes for cable and membrane structures. You will see – with RFEM, you enjoy structural analysis!

Quality of FEA Results

We are not friends of secrets and mysteries. Therefore, the Dlubal structural analysis software provides comprehensible structural analysis calculations. The "black box" character, as it exists in some other structural analysis programs, is left out here. You can see how the Dlubal software works, because we have nothing to hide. Here you can find numerous verification examples for our software programs that clearly show how the calculation methods work.

Interfaces for Data Exchange

The building information modeling process (BIM) is an essential part of their daily work for many civil engineers and structural engineers. Unfortunately, other structural analysis programs cause problems as soon as the word "integrity" is used. The structural analysis software from Dlubal, on the other hand, is different because it can be seamlessly integrated into the BIM process. Due to a large number of interfaces, you can exchange data from your digital building models with RFEM or RSTAB.

To read and write the data from or to RFEM and RSTAB, simply use the Webservice (a programmable interface). Thus, your data exchange works without any problems and you can reach your goal with just a few clicks.

Support and Learning

Our customers are important to us! For Dlubal Software, this motto is much more than that. Customer service is a fundamental pillar of the Dlubal Software company philosophy. We do our best to help you with any problems or concerns, so that you can continue to enjoy working with the Dlubal software programs.
