I have defined a wind profile for RWIND Simulation up to a height of 100 m. Is the wind profile dependent on the size of the wind tunnel?

Answer

In the wind profile, you always define the height ranges, for example, 0 - 5 m, then 5 m - 10 m, and so on. If your wind profile ends at 100 m, it is not cut off, but the value for 100 m is also applied for greater heights. If your wind tunnel is smaller than the stored profile, only the wind speeds up to this height are considered.

You can check this visually by displaying the velocity vectors and deactivating the display on a reduced area.

For a wind tunnel with a height of 50 m, you get the following result:

Image 01 - Wind tunnel height 50 m

For a wind tunnel with a height of 150 m, you get the following result:

Image 02 - Wind tunnel height 150 m
