Finite Element Analysis (FEA) Software

Finite Element Method (FEM)

The Finite Element Method (FEM) is a calculation method typical for the scientific and technical area. The FE method allows you to calculate complex problems that can hardly be solved by other means.

Since FEM is a numerical method for solving differential equations, it is possible to perform the finite element analyses (FEA) in various physical disciplines. A component subjected to FEA is subdivided into a large number of small finite elements with simple geometry so that the required quantity can be easily calculated. This subdivision provided the name for the numerical technique: Finite Element Method.

In structural engineering, finite element analysis applies FEM as a standard method for computer-aided calculation of beam and plate structures.

3D Finite Element Analysis and Design

The structural analysis program RFEM is the right software for user‑friendly application of the Finite Element Method in structural engineering. Efficient data input and intuitive handling facilitate modeling of simple and large structures. RFEM also provides solutions for structural and dynamic analysis of 3D structures.

RFEM is the basis of a modular software system and is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members.

In addition, it is possible to calculate internal forces as well as support forces. The program also allows you to create combined structures and model solid or contact elements.

Further analysis and design of components consisting of different materials in compliance with various standards can be performed in the corresponding add‑on modules.

Add-on Modules for RFEM

For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add-on module available for RFEM.

These modules allow you to perform nonlinear, stability and dynamic analyses as well as connection designs and form‑finding processes for cable and membrane structures.

Quality of FEA Results

Structural analysis programs by Dlubal Software provide comprehensible structural calculations. They are not a "Black Box". Numerous verification examples available on our website explain how the software works and reveal the calculation methods.

  1. Displaying FE Mesh Quality

    Displaying FE Mesh Quality

    As a new tool for structural analyses of two-dimensional components, a display function for the FE mesh quality was implemented in RFEM. When you perform an internal check of the generated finite elements for defined criteria, you can graphically display the result. It will be displayed in three different colors to illustrate the different levels of quality. You can edit all values of the criteria and thus adjust them to your individual needs.

    Using Result Beam in RFEM

    Since the release of RFEM 5, the ‘Result Beam’ member type has been available. The result beam is a virtual member that does not have any stiffness nor require any support. It can be used in various situations in order to integrate the results from members, surfaces, and solids, and to display them as member internal forces.
