Hello together,

I am trying to implement a turbulent channel boundary value problem using the Finite Element Method and the SA-Model in Mathematica (AceGen/ AceFEM). Do I have to compute 'd' in each node or in each gauss point?

Thanks and best regards

Wall distance in SA is needed in the source terms, so you need it wherever you use those source terms.
