Mesh Check Failed Problem
 

I am simulating a two-axisymmetric supersonic jet impinging on a flat plate. When I am rotating my mesh in fluent, mesh check is being failed every time.

I did perform a check command, still the same. (pdf attached)

Please, need help on this issue.

I think for axisymmetric your domain should be all with Y >0, but I see a -25 somewhere in the pic

Mesh Check Failed
 

Thank you, problem solved.
I made Ymin=0, now mesh checking is being fine.
