AnswerFirst information beforehand: If the program was started as a full version, it does not jump into the demo mode if the license cannot be found during the calculation or saving process.It remains in waiting stage until the license is available again.It is then necessary to distinguish the type of licensing.
For the single-user license, it should be checked if the hardlock was installed on the computer and if the indicator light situated at the end of the dongle is visible. If not, another USB port - preferably directly on the PC - should be used.In case of a network license, the problem might be caused by a failure in the network connection. In the web-based license user interface http://localhost:1947/_int_/devices.html, it should be checked if the license key is available there.Additionally, it is possible to look at the http://localhost:1947/_int_/features.html to see if a free license is available for the desired program or add-on module.If the licensing problem persists, you can create a diagnostic report from the warning message. Send it to our client support.

AnswerIf stiffeners are welded into the crane runway, the corresponding notch category according to EN 1993-1-9, Table 8.4, detail 7 has to be considered for the fatigue design. This is implemented in CRANEWAY by creating additional stress points at the connection point of the stiffeners to the section. They can be adjusted manually in the settings for the detail categories depending on the geometry of the stiffener.During the fatigue design of the craneway girder, the design of the axial stress range is additionally performed in the newly created stress points for the x-locations on which a stiffener is provided.
AnswerIn the case of long crane runways and many cranes, the large number of load combinations can lead to a long calculation time. The following settings affect the calculation time significantly:
Calculation method for determining the internal forces
The fast calculation type may therefore be useful for the preliminary design.
- Fast calculation (calculation of all load combinations according to the 1st-order analysis, then calculation of the governing load combinations according to second-order analysis for torsional buckling)
- Detailed calculation (calculation of all load combinations according to second-order analysis for torsional buckling)
Maximum target length of the finite elementsThe maximum length of the finite elements generated for the calculation according to the second-order analysis for torsional buckling can be entered within a range of 100 mm to 2500 mm. The calculation time can be increased significantly by the finer division of finite elements.Thus, you should select a reasonable length of the finite elements for an optimized calculation time depending on the structural system. Usually, 8 elements for each girder span are enough to calculate the deformations with a deviation of less than 5% relative to the precise solution.
Number of load combinationsYou can use a reasonable setting of the load increment to control the number of generated load combinations. When entering the load increment, the generated number of crane load positions and load combinations is already displayed in a preview. A small load increment may result in many load combinations that take accordingly more time in the calculation.
AnswerMake sure that no planned installation is currently performed. In the Task Manager, this can be displayed as an active app and as a background process called 'Windows Installer'.If a Windows Installer is still displayed in the Task Manager after restarting the computer, it can be selected and closed by clicking the 'End Task' button.Then, the desired installation can be carried out.
AnswerThe capacity of your C drive: no longer allows installation of the program. You must choose another partition of your hard drive for installation. You can proceed as described below:
- Start by displaying the "Run" command from the Start menu by clicking Start Menu> Run (or the Windows + R key)
- Type regedit and confirm
- Open the key: HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion
- On the right, double click on the key: ProgramFilesDir and modify the data of this key by the new path of the installation folder.
- For example, enter the path D: \ Program Files to change the partition on which the installation will take place.
- Finally, you restart the installation with a double-click on the icon.
We have received a NET softlock and have activated it successfully on the license server. However, the dialog box 'Authorization' appears after having installed the programs on the user PCs when the program is started. If I select the option 'Run Full Version' and refer to the authorization file, I get a message saying that the license has already been activated. What should I do?
AnswerIf no authorization file is already being used on the computer, the program tries to reactivate the softlock. However, as it is already active, the corresponding message appears. There are two ways to apply the already activated license to the clients.
- Select the 'Demo Version' option in the 'Authorization' dialog box and enter it as follows: Help -> Authorization -> Import Authorization File
- Rename the AUTHOR.ini file to AUTHORE.ini and save it in the directory C:\ProgramData\Dlubal\Global\General Data
AnswerIn CRANEWAY, you enter the exposure category declared by the manufacturer for each crane. For the fatigue design, CRANEWAY performs the designs for the individual damage as well as for the total damage from both cranes. According to EN 1993-6 chapter 9.4.2, the rule recommended in NOTE is applied. Considering two cranes, the exposure category of the crane with the lowest exposure category is reduced by 2 for the total damage.
Crane 1 S-Class: S6 Crane 2 S-Class: S5 Total damage S-Class: S3
AnswerGenerally, two things are required for the licensing:The license key can be provided via a USB dongle or by means of a network softlock on a central company server. For the licensing from perspective of a client, there must be a permanent connection to the server. Once a license has been assigned, it can be viewed on the web-based license surface at http://localhost:1947/_int_/sessions.html. An automatic timeout after 12 hours of inactivity prevents a license from being permanently assigned and releases it to other users.
With the most recent generation of license keys, it is possible to activate 50 licenses per program and add-on module. This means that you can access RFEM and RF-STEEL EC3 from a maximum of 50 computers at a time.
- license key
- corresponding authorization file
Whether or not the download for RFEM or RSTAB is displayed in the download area of the Dlubal account depends on whether or not you have concluded a service contract for the respective product.If a service contract has been concluded for the respective product, the links for this product are visible.If no service contract has been concluded, no links are visible.If you purchase RFEM or RSTAB without a service contract at a specific time, you are entitled to use this program version. If you need the download link for the purchased program version, you can download it on our homepage in the 'Previous Program Versions' section.See the link to 'Download Previous Versions' below:
AnswerThe setting of partial safety factors can be done by defining the National Annex of the standard in the General Data. The predefined National Annexes can not be modified, but it is very easy to create a user-defined National Annex.In this case, it is possible to adjust all standard-specific factors.
