Hi,Tom: Sorry for forgotting metioning that I compare both results with the experimental data, the rho*nu*gradU is at the same order with the experiment's, however, the wallShearStress returns a...

In fact, in LES, nuEff=nu+nuSgs, however, nuSgs on the wall is 0, so when we calculate wallShearStress, we can just ignore nuSgs. Additionally, the grid near...

In fact, my case is not laminar, but I don't think wallShearStress is just written for laminar only. I agree with you that the wallShearStress is actually the...

Two different values are obtained in the two ways, which one would be correct? Should we just use wallShearStress...
