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.
If the "Authorization" dialog box (Image 01) does not appear at the program start, an authorization file was imported at an earlier point in time.
In this case, select the "Diagnostics" option in the menu "Help → Authorization" (Image 02).
Save the text file, then open it. In File Explorer, set the path displayed under "PermDataDirectory" (Image 03). In this directory, you will find the AUTHORE.INI file. Delete this file.
When you start the program next time, the dialog box shown in Image 01 will appear. To activate the license, select the "Use full version" option. The license activation requires an Internet connection.
By clicking the following link, you can download a program that helps you to read both the dongle and the network dongle that are connected to the computer:
http://download.dlubal.com/?file=KeyDump.zip
Unzip the file named KeyDump.zip and run the KeyDump.exe file in the destination folder. You should see the dongle under "License Information" in the diagnostic program. If this is not the case, the dongle may be defective or the driver has not been installed correctly.
Normally, the dongle drivers are set up automatically during the installation. If this remains undone, the dongle driver can also be installed manually. The latest driver for your operating system can be downloaded here:
http://download.dlubal.com/?file=Sentinel_LDK_GUI_setup.zip
If the problem persists, please send us the log file, which you can create in KeyDump (see the image).
You should also note the following points:
The administration interface can be accessed at http://localhost:1947. No further installation is required, as this service is available after installing the dongle driver.
The Sentinel Keys option displays all Sentinel dongles. It is possible to access the server address by clicking one of these dongles. Our licenses are displayed with the vendor number 48521. If you select the Sessions option here, you can see which license is used by whom.
The license can also be withdrawn from a user in the "Actions" column.
