Hi all,
I am a beginner of CFD, recently I have read a paper said that"The maximum grid spacing in terms of wall units is Δx+=20 in streamwise direction, Δy+=19 in spanwise direction, and Δz+=1 near the dune surface." But I do not know the computational formula of the grid spacings Δx+,Δy+,Δz+, could you tell me the definition about it, or give me some papers to read? |
