Simulation of atmospheric boundary layer

Bazinga · February 18, 2014, 05:00

Dear all,

I am trying to have a simulation with an atmospheric boundary layer at the inlet. I was using the inlet conditions of the turbinesiting tutorial but I realized that the function atmBoundaryLayerInletVelocity sets Umax = Umax which is not what I want. I tried to delete the code which sets the velocity above Href to Uref but it didnt work for me.

Any ideas on how to create a ABL with the logarithmic velocity profile.

Thanks in advance

Have you looked at the swak4Foam libraries? They are handy for this sort of thing.
