The stand-alone program RWIND 2 takes care of fresh air. It is used for the numerical simulation of wind flow and is available in a Basic as well as a Pro version. What additional features does RWIND Pro offer you? It allows for the calculation of transient incompressible turbulent wind flows (in addition to the stationary ones in RWIND Basic). But that's not all. Intrested to learn more? Find out more here:

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)

Do you already know the editor for mesh refinement control? It is a great help for your work! Why? It's easy – it gives you the following options:
- Graphic visualization of the areas with mesh refinements
- Mesh refinement of zones
- Deactivating the standard 3D solid mesh refinement with transversion into the corresponding manual 3D mesh refinements.
These options help you to formulate a suitable rule for meshing the entire model, even for the models with unusual dimensions. Use the editor to efficiently define small model details on large buildings or detailed meshing areas in the coating area of the model. You will be amazed!
