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.
This warning might be caused by overlapping surfaces, which may occur when modelling one solid to another, for example (see Image 01).
In order to avoid the overlapping surfaces, an opening is required here. After defining the opening, also check if the definitions of the solids have to be corrected.
Automatic backup copies are stored in the working directory in a folder with the same name as the model you have processed. This folder contains all the files created when entering the model data and performing the calculation, including the backup file Position.bak (see Image 01).
Copy the Position.bak file to another folder and rename it "Modell.rf5" or "Modell.rs8". Thus, you can open the file with RFEM or RSTAB.
The Position.bak file is automatically deleted when quitting the program properly. However, when you open RFEM/RSTAB after the program crash, a message appears asking whether the backup file should be opened again.
RFEM/RSTAB have an integrated backup function. You can find it in the working directory of the program. The current models are created here as subfolders of the program version. They contain all the files created during the input and calculation, including the backup file Position.bak.
The working directory is created after the installation. You can find the file location using the menu "Options → Program Options" in the "Data Files" tab when setting the Working Directory category.
The Position.bak file is automatically deleted when you quit the program properly. However, if the program crashes, the file still exists. You can restore it as described. When you open RFEM/RSTAB after a program crash, a message appears asking whether the backup file (Position.bak) should be opened again. Click [Yes] to confirm and the backup file will be loaded.
You can define the interval of automatic file saving using the menu "Options → Program Options" in the "Program" tab.
