Convergence issue with fine grid -- CFD Online Discussion Forums

June 27, 2009, 03:02	Convergence issue with fine grid	#1
itisharisankar New Member hsan Join Date: Jun 2009 Posts: 1 Rep Power: 0	Hi All, 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. Regards Hari
