- Run RWIND Simulation "As Administrator". To do this, right-click the RWIND Simulation icon and select "Run As Administrator".
- Click the "Activate Now" button to confirm the authorization check.
Then, the "RWIND Simulation 1.xx Demo Authorization Status" dialog box appears. - In the "RWIND Simulation 1.xx Demo Authorization Status" dialog box, select the "Software key" option in the Authorization Method section and click the "Activate Online" function in the lower part.
This opens the "Online Activation" dialog box. - In the "Online Activation" dialog box, enter your license information (license number, activation key, and level of RWIND Simulation) based on your contract documents.
In addition, enter the expiration date of the activation to be carried out in the middle field and the user-defined description of the work center to be activated in the bottom field.
Then, click the "Activate Now" function to run the activation process.
Upon successful authorization, you will receive a confirmation message and it will be possible to 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 technical article.
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.
