A.M.Memarzadegan Guest Posts: n/a	I am to Validate my code by solving backward-facing step flow(turbulent). i used kim et al stepflow.I found the problem so dependent to grid generation.when i change the grid of corner of step i obtain different reattachment point. I Wonder if anybody knows a good grid for backward-facing step flow. the inlet length is 4step height the inlet dia=2step height and the total length is 28*step height the inlet velocity is uniform while k & eps prescribed .Re=69610 the k-eps model with wall function has been used. Kind Regrads, A.M.Memarzadegan
