Hi all,

I'm using a user-defined nonlinear v2-f turbulence model. I'm currently using a wall boundary condition of specified flux of 0 for the Reynolds Stresses, but the Reynolds Stress profiles at the wall are not matching those from FLUENT's Reynolds Stress Model (and consequently, the skin friction coefficient and velocity profiles aren't matching the RSM, k-e, k-w, or SA models.)

The FLUENT manual says how it defines the Reynolds Stress boundary conditions for the RSM model, but they involve wall-tangential and wall-normal directions, which I don't know how to compute using UDFs.

So my question is: does anyone know how to specify Reynolds Stress boundary conditions in FLUENT?

Thanks!
