Solution won't iterate ?!?!?
All,
When I try to iterate fluent freezes and does nothing for hour(s). Has anyone else ever had this problem? Is there anything that I can do to get around this? The details of my problem follow: PURPOSE : -Comparison study between the FUN2D and Fluent flow solvers GRID INFO : -Create using AFLR2 for FUN2D -Converted to Gambit neutral file using fortran code that i wrote -2d -Imports into fluent w/ no problems -195796 Cells -Every thing checks out when performing grid check in fluent -Minimum wall spacing is 2e-6 such that y+<1 SOLVER SETTINGS : -Inviscid works fine...problem iterates to a solution -Turned on Spalart-Almaras (which is what is used in FUN2D) and when tried to run Fluent stops dead in it's track Any help at all would be greatly appreciated. Thanks, greg |

Re: Solution won't iterate ?!?!?
I left out some important details...The grid near the wall is HIGHLY skewed ~0.99. Could this possibly be the culprit??
