The structural analysis software RFEM 6 is the basis of a modular software system. 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. The program also allows you to create combined structures as well as to model solid and contact elements.
RSTAB 9 is a powerful analysis and design software for 3D beam, frame, or truss structure calculations, reflecting the current state of the art and helping structural engineers meet requirements in modern civil engineering.
Do you often spend too long calculating cross-sections? Dlubal Software and the RSECTION stand-alone program facilitate your work by determining section properties of various cross-sections and performing a subsequent stress analysis.
Do you always know where the wind is blowing from? From the direction of innovation, of course! With RWIND 2, you have a program at your side that uses a digital wind tunnel for the numerical simulation of wind flows. The program simulates these flows around any building geometry and determines the wind loads on the surfaces.
Are you looking for an overview of snow load zones, wind zones, and seismic zones? Then you are in the right place. Use the Geo-Zone Tool to determine quickly and efficiently snow loads, wind speeds, and seismic data according to ASCE 7‑16 and other international standards.
Would you like to try out the capabilities of the Dlubal Software programs? You have the opportunity to do so! The free 90-day full version allows you to thoroughly test all our programs.
As of April 2017, we only provide 64-bit versions of our software. The last versions, which are still available as 32-bit versions, are RFEM 5.07.13 and RSTAB 8.07.13.
If you are still using 32-bit Windows, we recommend that you switch to the 64-bit version of Windows. This operating system version runs on virtually all computers. Windows 64-bit allows you to use much more RAM, which is a big advantage for our software.
First, it is necessary to ensure that the current RFEM/RSTAB version and the Revit version are on the same level. In the best case, you have installed the latest version of each.
If the plugin in Revit is still missing, you can install it as follows:
1. Go to the following folder, according to the system:
2. Open the DLInstaller.exe program.
3. Go to the "Diagnostics" tab and click "Start".
4. If this does not solve the problem, please send us the report that is generated via "Show Log".
The current versions of RFEM and RSTAB are only available as 64-bit versions. We recommend using the 64-bit version of Windows. This should be possible without problems.
If you still want to use a 32-bit version of RFEM or RSTAB, you can download the previous versions using these two links:
The 32-bit equation solver is selected in Calculation Parameters (see the image). You have probably used an older file as a template. The 32-bit solver can use a maximum of 2 GB of RAM, no matter how much RAM the computer actually has.
If you select the 64-bit solver, the calculation will run smoothly.
