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.
In case of a crash, a backup file is automatically created by RFEM. This file is not directly available to the user but can be restored when restarting the program. RFEM will prompt a dialog box asking if you want to Delete or Restore the file (Image 1).
If you select Restore, the automatic backup file is restored. The automatic backup file is dependent on the the time defined in Program Options & Settings (Image 2).
If you select Delete, your model will be opened from the point of your last manual save.
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.
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 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.
The project file is usually unaffected when updating. Moreover, when you uninstall the program, no models are deleted. Only the links contained in the Project Manager will be lost during the uninstall. However, they are retained in the case of an update.
User-defined toolbars, settings for display properties, and so on, can be saved in the Configuration Manager (see image). This backup file can then be easily restored in case the settings are lost.
The program carries out an automatic data backup. You can set the interval for saving the file Position.bak in the menu "Settings → Program Options" in the "Program" tab. The interval is set to two minutes by default (see Image 01).
The automatically created backup copies are saved in the working directory and recovered in the case of a program crash when opening the program again. If you quit the program properly, this backup copy will be deleted.
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).
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.
In order to avoid starting from the beginning in the case of a corrupt file, it is worth taking a look at the backup files, which are created automatically by the program. There are two different backups that are described in detail here. If this does not help, you can send us the corrupt file. Under certain circumstances, it can be saved.
In Project Manager, there is the option to save selected models or an entire project in a compressed backup file.
Select the model or project that you want to archive. Then, open the menu "Archive Data → Make Archive".
In the following dialog box, you can specify whether the results and printout reports should also be archived (see image).
After entering the desired file name and defining the path, start the archiving with OK.
