Structural Analysis Engineering Software
Structural FEM Analysis and Design
The structural analysis software RFEM 6 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.
Structural Frame & Truss Analysis Software
The structural frame and truss analysis software RSTAB 9 has similar functions as the FEA software RFEM. Due to the special attention to beam, frame, or truss structures, it is very easy to use and for many years, it has been the best choice for structural analysis and design of pure structural member models.
Wind Simulation and Wind Load Generation
The RWIND 2 stand-alone program is recommended for complex structures. Utilize this program to simulate wind flow (digital wind tunnel) around buildings or any other objects and generating wind loads, that is the forces acting on these objects based on CFD.
Import the generated wind loads acting on these objects to the structural analysis and design software RFEM or RSTAB.
Add-ons and Add-on Modules for RFEM and RSTAB
For design of various materials such as reinforced and prestressed concrete, steel, aluminium, timber, and glass, there is a wide range of powerful add-ons and add‑modules.
They allow you to perform nonlinear, stability and dynamic analysis as well as joint design and form‑finding process for cable and membrane structures.
Section Properties of Any Cross-Section
The RSECTION 1 program determines cross-section properties, analyzes stresses, and performs plastic design of any cross-section.
The Effective Sections extension for RSECTION determines effective sections according to EN 1993‑1‑5 and EN 1993‑1‑3. The cross-sections and the calculated cross-section properties can be exported to RFEM or RSTAB.
Stand-Alone Programs
The stand-alone programs do not require the installation of the main programs RFEM or RSTAB.
CRANEWAY designs craneway girders according to EC 3 and PLATE‑BUCKLING performs buckling analysis for unstiffened and stiffened rectangular plates according to EC 3.
The RX‑TIMBER programs design glulam trusses, continuous beams, columns, purlins, frames, stiffening, and roofs of timber structures.
Interfaces for Data Exchange
The structural analysis software provided by Dlubal Software can be integrated seamlessly into the Building Information Modeling (BIM) process. The large number of interfaces ensures the data exchange of digital building models with RFEM or RSTAB.
The web service (programmable interface) can be used to read or write data from/to RFEM and RSTAB.
Support and Learning
Customer service is a fundamental pillar of the Dlubal Software company philosophy. We provide any necessary support you need to complete your daily work.

Automatic Preliminary Form-Finding of Membrane Surfaces
Activating the "Show Preliminary Form-Finding" option in the shortcut menu leads to an automatic preliminary form-finding according to the saved form-finding properties when you change the structure of membrane surfaces. This interactive graphics mode is based on the force density method.
- For the design, I can only select the surrounding reinforcement for a rectangular cross-section. Why?
- Some of my supports are rotated by 180 degrees. How can I rotate the view of a nodal support?
- I would like to enter a large spring constant. Is this possible?
- Is it possible to switch off the minimum internal forces when displaying a result diagram so that only the maximum values are displayed?
- I do not want to design a cross-section in the RF‑/STEEL EC3 add-on module. Can I quickly remove this cross-section from the selection?
- I am designing a set of members using the equivalent member method in RF‑/STEEL EC3, but the calculation fails. The system is unstable, delivering the message "Non-designable - ER055) Zero value of the critical moment on the segment".What could be the reason?
- How can I display the internal forces in the global coordinate system and not in the principal coordinate system of the cross-section?
- I would like to define a line support with ineffective tension and apply the tension force on this line using a nodal support instead. Why does the line support still receive a tension force?
- Does the program check the lap length of the vertical stirrups of a block foundation with smooth bucket sides?
- A single-span beam consisting of several apparently straight members receives small torsional moments in the load case of "dead load". Why?
