Hello Everyone,

I am a new member on CFD online.

I am facing a problem combustion Transition piece casing flow analysis.

I have done hexa blocking mesh in ICEM.
Geometry is very complicated, so I m not able to do much quality in blocking but I have done quality improvements by global smoothing.

When I am importing the mesh in fluent I am getting WARNING: high aspect ratio cells may cause problems for wall distance..............n so on.

But mesh check is ok.

When case is running with default URF, continuity diverging and it stops at 80 iterations.

But, I have tried with reduced URF, It was running but not converged solution.

If it is running with Reduced URF means, is mesh ok or not ok??

After smoothening I Have angle 9 and quality is 0.1.

Please give your suggestions,


Thanks in Advance,
