mean boundary values for unsteady statistics
Hi,
I'm experiencing a strange things with a transiant LES simulation over a smooth stationnary wall. When I plot the distribution of the instantaneous stream velocity (say u) the non-slip condition is satisfied on the wall of the computational domain (u=0 at the wall). But when I plot in the unsteady statistics menu the mean x velocity (<u>) on the nodes values the non slip condition is not satisfied (<u> /= 0) ! Is it a bug or ? And what about the friction velocity calculated by Fluent in this cas, because the normal gradient to the wall for y=0 is not correct here ? I'm using the RNG Smagorinsky formulation for the LES with y+ ranging from 0.01 to 2.5. Any help will be appreciate. Thank's a lot. Francois |
