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.
A calculation break‑off due to an unstable system can have different reasons. On one hand, it can indicate a "real" instability due to overloading the structural system; on the other hand, modeling inaccuracies may also be responsible for this error message. In the following text, you can find a possible procedure for finding the cause of the instability.
1. Modeling Check
2. Check of Stiffening
3. Numerical Problems
4. Detecting Causes of Instability
Submit your current proof of enrollment and we will provide you with a full version of our software, valid for 1 year. When your license expires, you can extend it for an additional year by submitting updated proof of enrollment at your college or university.
For working with RFEM and RSTAB, we recommend a graphics card that accelerates the OpenGL functions on the hardware side. This is the case with all current graphics cards.
We recommend cards equipped with an NVIDIA graphics processor. However, RFEM and RSTAB do not necessarily need CAD high-performance graphics cards (NVIDIA Quadro ...).
The drivers of the graphics cards must always be kept up to date.
The drivers of mainstream graphics cards (NVIDIA GeForce ...) are better tuned by the driver to different computer configurations, which is why there are far fewer problems with these than with CAD cards. We do not recommend graphics solutions that are integrated into the chipset or main processor (Intel HD xxxx, G xx, Qxx).
Notebooks are often equipped with two graphics chips; a power-saving Intel HD chip integrated into the processor, and an additional powerful graphics chip (for example, from NVIDIA or AMD). In this case, it is necessary to ensure that RFEM and RSTAB use a powerful graphics chip.
