I have a problem with RNG k-epsilon turbulence model.

I want to simulate 3-D Pattern of flow at a lateral intake in straight open channel.When I use RNG turbulence Model I can't converge the solution (I use the difrential viscosity and Swirl... options). can everybody help me? thanks

Chek Y+ on the walls. Its value should not bellow 30 and should between 30 to 200. Use the differential viscosity model if in your case the low Reynolds number effects is considerable.

Hope this help you
