Convergence issue with fine grid
Join Date: Jun 2009

I am trying to study the flow of a fluid inside a circular duct using FLUENT.
I have meshed the geometry using HEX elements.
I am using K epsilon turbulence model with enhanced wall functions.
I have kept 3 cells below y+ < 5 range for Re = 1,00,000 and the solution converged.
But when I use the same mesh for Re = 50,000, continuity equation is not converging. ie Y <<1
Can any body help me out in this issue.
