Hello
I want to simulate the flow around a building in atmospheric boundary layer with the turbulence model K-omega SST. In this case , are functions of the height .

How can I specify theses boundary conditions at the inlet as a function of the height ?

Hello Evren

Did you have a look at the tutorial case "turbineSiting"?

It uses ABL settings for U and k-epsilon, so it can be a good basis for your case but you'll probably have to implement sth. like "atmBoundaryLayerInletOmega". If you check "atmBoundaryLayerInletEpsilon" details, I am sure you can figure it out since the core implementation is done at "atmBoundaryLayer" under:

$FOAM_SRC/TurbulenceModels/turbulenceModels/RAS/derivedFvPatchFields

Check "atmBoundaryLayer" for ABL implementation:

[ertinaz@supernova derivedFvPatchFields]$ ls atmBoundaryLayer -l
total 16
-rw-rw-r--. 1 ertinaz ertinaz 4643 Jan 19  2018 atmBoundaryLayer.C
-rw-rw-r--. 1 ertinaz ertinaz 7083 Jan 19  2018 atmBoundaryLayer.H

Hope this helps
