- Run RWIND Simulation "As Administrator". To do this, right-click the RWIND Simulation icon and select "Run As Administrator".
- Select the "RWIND Simulation - License and Authorization" function in the "Help" menu.
This opens the "RWIND Simulation 1.xx Authorization Status" dialog box. - Check in the "RWIND Simulation 1.xx Authorization Status" dialog box to see 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.
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, the activation period for a license cannot be extended.
If the requirements mentioned above have been met, click the "Extend Activation Online" button. The "Extend Activation Online" dialog box appears. - The "Extend Activation Online" dialog box shows the license specification to be extended.
Enter your online activation key based on your contract documents and define the new activation period in the date field.
Then, click the "Extend Activation Now" function to run the online extension.
This opens the "RWIND Simulation 1.xx" dialog box. - In the "RWIND Simulation 1.xx" dialog with the confirmation prompt about the planned modification, click "OK" to finally change the activation period.
Upon successfully changing the activation period, you will receive a confirmation message and can use the program without restrictions.

In RFEM and RSTAB, you can visualize the flow field quantities of pressure, velocity, turbulence kinetic energy, and turbulence dissipation rate for the wind simulation.
The clipping planes are aligned with the respective wind direction.
If you have experimentally determined surface pressures available for a model, you can apply them to a structural model in RFEM 6, process them in RWIND 2, and use them as wind loads in the structural analysis of RFEM 6.
You can find out how to apply the experimentally determined values in this Knowledge Base article: Static Analysis with Wind Loads from Experimentally Measured Pressures Using RWIND 2 and RFEM 6
You can display the RWIND results directly in the main program. In the Navigator - Results, select the Wind Simulation Analysis result type from the list above.
Currently, the following results are available, which refer to the RWIND computational mesh:
- Surface pressure
- Surface cp coefficient
- Wall distance y+ (steady flow)
Use RWIND 2 Pro to easily apply a permeability to a surface. All you need is the definition of
- the Darcy coefficient D,
- the inertial coefficient I, and
- the length of the porous medium in the direction of flow L,
to define a pressure boundary condition between the front and back of a porous zone. Due to this setting, you obtain the flow through this zone with a two-part result display on both sides of the zone area.
But that's not all. Furthermore, the generation of a simplified model recognizes permeable zones and takes into account the corresponding openings in the model coating. Can you waive an elaborate geometric modeling of the porous element? Understandable – we have good news for you then! With a pure definition of the permeability parameters, you can avoid complex geometric modeling of the porous element. Use this feature to simulate permeable scaffolding, dust curtains, mesh structures, and so on.
