We provide hints and tips to help you get started with the RFEM program.
RFEM - FEM Structural Analysis Software
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.
RFEM - Powerful, Easy, and Intuitive
First Steps with RFEM
RFEM is a powerful 3D FEA program helping structural engineers meet requirements in modern civil engineering. Efficient data input and intuitive handling facilitate modeling of simple and large structures.
The structural analysis program RFEM is the basis of a modular software system. The main program RFEM is used to define structures, materials, and loads for planar and spatial structural systems consisting of plates, walls, shells and members. The program also allows you to create combined structures as well as model solid and contact elements.
RFEM provides deformations, internal forces, stresses, support forces, and soil contact stresses. The corresponding add-on modules facilitate data input by automatic generation of structures and connections or can be used to perform further analyses and designs according to various standards.
The modular software concept allows you to compile a program package tailored to your individual needs. It is possible to upgrade the program at any time.
Due to a wide range of interfaces, RFEM provides perfect interaction between CAD and structural analysis programs in Building Information Modeling (BIM). Thus, the bidirectional data exchange between RFEM and the programs Tekla Structures, Autodesk Revit and Bentley ISM is possible, for example.
“Great praise again, I really enjoy my structural analyses with RFEM. Your advertising slogan is actually true.”
"'The spatial FEA model offered very good options to analyze and design the load-bearing behaviour of a special complex structure in a verifiable way. Due to the extremely high safety requirements concerning the most famous landmark of Germany, the Brandenburg Gate, it was necessary to mount the support structure in two stages. The specific mounting situations could be modelled very well in RFEM.'"

Frequently Asked Questions (FAQs)
- How can I import an IFC model into the RWIND Simulation environment?
- After opening a duopitch roof beam from RX‑TIMBER in RFEM/RSTAB, it is displayed with a gap in the apex zone. Does this affect the calculation?
- How can I additionally model welds for the connection of two surfaces with a contact solid?
- Is it possible to display the results of shear forces on a member in the horizontal plane?
- RFEM cannot be started. What could be the reason for this?
- I would like to analyze cable and tensile structures. Is it possible to use RFEM or RSTAB for this?
- Which add-on modules and programs do I need for laminate and sandwich structures as well as cross-laminated timber (CLT)?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- When calculating a membrane, the resulting deformation of the load case LC1 and the combination CO1 differs, although the combination CO1 only contains CO1 with the factor of 1.00. What is the reason for this?
- How can I enter a member elastic foundation that only acts in one direction?
