June 17, 2011, 07:43	Naca 0012 (compressible and inviscid) flow convergence problem	#1
bipulsaha New Member Bipul Saha Join Date: Jun 2011 Posts: 1 Rep Power: 0	I am currently modelling Flow around a 2D airfoil using Fluent 6.3.I have created 3 mesh geometries(coarse,medium,fine) in gambit and i am modelling it for 3 cases subsonic ,transonic and supersonic.I have gone through the fluent tutorials and have read a lot on the web on how to perform such simulations.But the problem is although i am getting almost accurate coefficient of lift,drag and pressure but my results are not converging. I am using a density based solver and the flow is compressible and inviscid.Material is ideal gas and the cfl number i am using is .1. Can someone please help me out.It will be a great help. sherlock likes this.
