  • Answer

    The RWIND Simulation program is protected against unauthorized use. The application works without restrictions on a single-user computer, where the license based on a software key has been activated. To release the assigned license (for example, to use it on another single‑user computer), you can deactivate the license on the license-holding single-user computer offline via e‑mail. Proceed as follows:

    1. Run RWIND Simulation "As Administrator." To do this, right-click the RWIND Simulation icon and select "Run As Administrator."

      Figure 01 - Program Start

    2. Select the "RWIND Simulation - License and Authorization" function in the "Help" menu.

      Figure 02 - License and Authorization Settings

      This opens the "RWIND Simulation 1.xx Authorization Status" dialog box.

    3. Check in the "RWIND Simulation 1.xx Authorization Status" dialog box if an active software key authorization is available. This is the case if the "Software Key" option is selected in the "Authorization Method" section, and an active authorization is indicated by a green dot in the "Authorization Status" section.

      Figure 03 - Authorization Status

      If the check is negative, and a red dot is displayed, no RWIND Simulation license based on a software key is activated on the single-user computer. As a result, no license can also be deactivated.

      If the requirements mentioned above are met, click the "Deactivate via E‑Mail" button. The "Deactivation of RWIND Simulation" dialog box appears.

    4. The "Deactivation of RWIND Simulation" dialog box explains the deactivation process.

      Select the "Deactivate RWIND Simulation Now" function.

      Figure 04 - E-mail Deactivation

      This opens the "RWIND Simulation 1.xx" dialog box.

    5. In the "RWIND Simulation 1.xx" dialog box, click "Yes" to confirm the license deactivation.

      Figure 05 - Confirmation Prompt

      After the successful deactivation, you will receive a confirmation message. Now, you can only use the program in the demo mode.

      The "Deactivation of RWIND Simulation" dialog box opens again.

    6. The deactivation code is now displayed in the "Deactivation of RWIND Simulation" dialog box. Copy this text block to the Windows clipboard with the "Copy to Clipboard" function and then paste the code into a blank e‑mail with [Ctrl]+[V] or the Windows paste function. Send this email to support@dlubal.com to complete the license deactivation.

      With this code, we document a proper deactivation in our system.
    You can now reactivate the released license on another single-user computer.

First Steps

First steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

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.

Your support is by far the best

“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. ”
