Hello All,

I am doing a validation study on a backward-facing step and trying to implement k-epsilon with proper boundary conditions. The dynamic viscosity for the problem is 1.96*10^-6 N.s/m2, Re 5100, density 1kg/m3, Ux=1m/s, Uy=0. I have made the proper mesh according to y+ NASA calculator. I have 29000 number of nodes for the mesh. Everything is being step properly. Now, I want to implement k-epsilon with a give value of k=0.015m2/s2 and turbulence intensity of 10%. The aim of the study is to compare my data with the reattachment point. I have tried to set up k and epsilon properly. However, the results do not seem reasonable. I am attaching both k and epsilon boundary conditions and would be more than happy if someone of you could help in this regards.
