hi me again...i finally managed it to run my channel flow. i put the boundary conditions for outlet and inlet both to outlet(fixed pressure and rest zero gradient) for the walls i use wall functions. now with k-epsilon and rng k-epsilon it works well and it converges after 10000 iterations with simple foam. now with the non-linear k-epsilon i made 30000 iterations and the profiles still look weird.....does it just take more time because of the more complicated turbulence model?
whatever with the rs-models like LRR notheing is working. always comes this error message:

Reading field p

Reading field U

Reading/calculating face flux field phi

Selecting incompressible transport model Newtonian
Selecting turbulence model LRR

what should i do?
maybe someone can help me
