ICEM CFD: Concentric cylinder
 

Hi everyone,

I am new to ICEM CFD and trying to learn it. I have done a few tutorials and to test my own understanding, I created a concentric cylinder and tried to mesh it.
I was able to complete it but when I tried to export the mesh to Fluent, it showed an error message. I have attached the images.
Any idea why the error message is popping up?
Is it because it is of low quality?

Thank you.

I removed the biasing of radial direction near the outer surface and the problem is solved!
I am able to import to Fluent now and shows good quality too!
No idea why it happens though!
