 Sci Advisor P: 1,498 Well, having said that, you could just kind of substitute height for height above the surface, e.g. Rather than $$u(i,j,k) = log(z(i,j,k))$$ Have something like: $$u(i,j,k) = log( z(i,j,k) - z(i,j,1) )$$ Do remember that boundary conditions are quite a problem in most computational codes, and many many problems can arise from them. Having said that, be very careful when analyzing results such that you ensure you're getting what you think you should. I image there could be problems with reflections depending on the actual boundary condition implementation.
