The mesh look fine, but when I go and look at the quality of the mesh, it shows the element having uality ever lower than 1, as shown in the attached figure. Furthermore, the aspect ratio is higher 5 in thousands. Can anyone please advise, what step shall I choose to improve the quality. I am very much struglling. Ansys CFX is accepting this kind of mesh.

I have attached few figures that might help in elaborating the respected request.

Please help!!!

Many thanks,
