Default Solution won't iterate ?!?!?
Posts: n/a

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:


-Comparison study between the FUN2D and Fluent flow solvers


-Create using AFLR2 for FUN2D

-Converted to Gambit neutral file using fortran code that i wrote


-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


-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

I left out some important details...The grid near the wall is HIGHLY skewed ~0.99. Could this possibly be the culprit??
