cedrik is on a distinguished road
Hi dear foamers,
I'm trying to perform a simulation of wind comfort on a building but there is something I can't explain.
I performed the turbineSiting tutorial as a training. I cut off the snappyHexMesh and the toposetDict (on adapting all the files of and system) and I ran the tutorial (with an empty blockMesh).
Here is the problem : why U is not the same everywhere at a fixed altitude?(screnshots attached; z = 1000m).
Thanks for your help,

Greetings Cedric,

I think you need to do some more studying in the field of Fluid Dynamics, before continuing with these simulations .
I say this because if you look at a section cut over Y, it should be self-explanatory, as shown in this attached image:

For example, have a look into the topic "Boundary layer" on Wikipedia:

Best regards,
