AnswerThe detailed instructions for transferring the virtual dongle to another server are included in the PDF file below.
AnswerThe IP address of the server can be found in the "Admin Control Center" (ACC) at the following address:
The IP address is displayed as soon as you move the mouse pointer over the server name (see Figure 01). If there are several dongle types displayed, make sure that the vendor ID 48521 is shown and the "Net" term is included in "Key Type."
In the case of a single user license , the user works with the programs licensed to his workstation. Use of the licenses is controlled by a key (USB hardlock, also known as dongle or softlock). The key is installed directly on the computer of the respective workstation. Instead of the USB hardlock, software (softlock) can also assume the protective function. The corresponding authorization file (author.ini) is used to control which programs can be operated with the respective key.The advantage of such a single-user license is that the user always has exactly the same configuration of the programs available in the form of a key. No one else can use or block the programs at the same time. Using the programs can be easily transferred from one computer to another, for example, by a USB hardlock. The prerequisite is that the programs have been installed once on the computer with the corresponding authorization.The same thing works with the softlock. Here, the relocation procedure is only a bit more complex and can be carried out by means of software. Single-user licenses are particularly advantageous for smaller offices with fewer users who always work with the same software configuration.For a network license, the license protection is activated by means of a special network key. It is also available as USB hardlock or softlock. The network key can be attached or installed on any computer that can be reached in the network. A special license manager then controls the access to it. The Dlubal software itself is installed as is the case with the single-user license. The authorization file then specifies that the protection key is searched for in the network.The advantage of the network license is that it is no longer necessary to change/move the key from one workstation to an other. Once the software has been installed, it can also be used as long as one license is free and not already used by another user. Another significant advantage is that the respective features of program modules can be better adapted to the requirements. Less frequently used add-on modules can be purchased in smaller numbers than number of employees who have to be able to work with them. The likelihood is low that another employee will use the license at the same time. Thus, add-on modules can also be shared with each other. Due to the option to use softlocks, it is also possible to use them on virtual machines. If network licenses are used, you can also access the Dlubal programs remotely, for example by using Remote Desktop. Since not everyone has a physical access to the server, the license is also better protected against theft, for example, and you do not have to search for it with other employees.Network licenses are now the standard for larger companies with several employees.
ExampleSingle-User LicenseEmployee A works in reinforced concrete area:RFEM, RF-CONCRETE, EC2 for RFEM, RF-PUNCH Pro, RF-CONCRETE ColumnsEmployee B works in the steel construction sector:RF-STEEL EC3, RF-STABILITY, RF-DYNAM - Natural VibrationsEmployees A also need access to the RF-DYNAM Basis, so they have to get the key from employee B. However, he can not process any reinforced concrete structures.Compare network license with the same equipmentTwo licenses RFEM, RF-CONCRETE, EC2 for RFEM, RF-PUNCH Pro, RF-CONCRETE Columns, RF-STEEL EC3, RF-STABILITY, RF-DYNAM Natural VibrationsEach employee can use the full range of add-on modules as long as the other employee is not working with them at the same time. The license is only used if the add-on module is open (in use). For example, it would also be possible to edit a structural system with mixed steel and concrete materials.Due to the increased usability and flexibility of the add-on modules, network licenses are associated with an additional charge of approx. 25% of the initial license price (all prices are listed in the webshop).
AnswerYes, this is possible. In addition to the conventional hardlock dongle (USB dongle), it is also possible to use a softlock dongle. A virtual fingerprint is created for the identification and thus, the license is linked to the computer or to the virtual machine. It is important to pay attention to the properties described under the link below.
It is not possible to outsource the calculation to a cluster for RFEM.
A possible way to relieve the workstation computer of complex calculations is as follows: RFEM is installed on a well-equipped terminal server .
Each employee, who has to perform complex calculations, will be provided with an access to the server via Remote Desktop.
This option requires network licenses.
Unfortunately, this is not possible. Both the access via Remote Desktop and the use of virtualization software are planned and blocked.The solution to this problem is to use a network dongle. In this way, you can also access the license by using Remote Desktop or a VM. Please inform yourself at our sales department about a dongle conversion.
Dongle servers are not supported for local dongle by our dongle manufacturer (Gemalto). Thus, when using a dongle server, we can not guarantee functionality or support. If you want to access a license from several computers, a network dongle is required. Contact our sales department.
The installation of RSTAB and RFEM on a terminal server is possible.
The prerequisite is a network license.
AnswerThe online service "Snow Load Zones, Wind Zones and Earthquake Zones" is an interactive website that uses a script code to calculate the results and the Google Maps API to display the map graphics. To use it, you must at least trust dlubal.com.
The following procedure must be used to remove the cloned license:
1. Go to http: // localhost: 1947 to access the Admin Control Center (ACC).
Second In the "Admin Control Center" (ACC), locate the target license "Sentinel SL AdminMode".
Third Click on the "Certificates" button on the right side of the SL description.
4th Record the name of the corresponding certificate and the path to the certificate base in the Certificates section: The default path is: C: / Program Files (x86) / Common Files / SafeNet Sentinel / Sentinel LDK / installed
5th Delete the certificate file in the directory C: / Program Files (x86) / Common Files / SafeNet Sentinel / Sentinel LDK / installed
6th Restart the server.

Wind Simulation & Wind Load Generation
With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.
The generated wind loads acting on these objects can be imported to RFEM or RSTAB.
“Thank you for the valuable information.
I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
