Fluent-gridgen axis abnormalities (screencap attached)
 

Hello,

I have created a 3D structured mesh in gridgen- a quarter of a nozzle (with periodic boundry conditions).
The believe the axis domains required for creating the blocks cause the problem.

I imported it to fluent and I get non-physical results near the axis

how can I solve this issue?

Thanks,

anyone?
 

I have created a new mesh using ICEM and got the same results.
The problem is in fluent..

What can I do?

Did you review the boundary conditions in fluent to make sure everything is correct?

yes I did.

2 symmetry planes,
1 pressure inlet
1 pressure outlet

just a regular nozzle...
