Hi foamers,

I wish you a happy new year!

Here is my first problem for 2015 :

i created a test case for a channel flow where the upper and lower boundaries are no slip walls, back and front are inlet and outlet and the side patches are symmetry planes. I want to use dbnsTurbFoam (with local time stepping) and RS turbulence modelling with wall functions.
I use first order discretization for turbulence and roe/venkatakrishnan for rho, rhoU and rhoE (second order).
The attached image shows the case with very strange near wall results.

What i tried:

- no turbulence modelling (works fine)
- using k-epsilon model (even worse, see picture)
- first order discretization (no improvement, very strange right?)
- different limiter (no improvement)
- global time stepping (- " -)

In the simulation i'm actually trying to perform the boundary layer is not as bad as in the test case. But still oscillations in wall normal directions. I think this is due to the fact that the walls end in the domain and not at the outlet (worst results in test case).

I would really appreciate your advises.
