C.C Member CC Join Date: Jun 2011 Posts: 73 Rep Power: 14	Dear all, I'm simulating a non-newtonian fluid flow with a low-Re k-e turbulence model, AKN model. I implemented it using an UDF. If I chose the wall B.C. flux equal to zero for epsilon the results are different than that if I chose the value equal to 2KinematicViscosityk/SQR(WallDistance). Anyone can help me with this question wall B.C. for epsilon.
