i am working on ansys fluent...i have generated a mesh of perforated plate but eacb time i check the quality of mesh the warning comes" maximum cell skewness exceeds 0.98." i have tried different minimum and maximum sizes of cell but unable to resolve the problem.....please if anyone knows the solution help me.....it would be a very great favor....please...

This problem is due poor meshing, try the following....
check for hexahedral elements in 3D or quadrateral elements inn 2D. Also check for the refining methods.

[Adila Anbreen]

how am i supposed to do that?
i am using ansys fluent 12.1 and in ansys 12, meshing method can be changed and i have tried all methods one by one... i did not find anything where i can change the shape of meshing elements...
option of refining the hexahedrals is available in earlier versions of ansys but i could not find it in ansys 12.
if you can help in improving mesh quality in ansys 12, it would be so nice of you...

well I am using ansys 14.0 and there is lot of options available for improving the geometry.
let me know your geometry and I will try to solve it but keep in mind that it also depends much on how complex is your geometry.
You can mail it to me

Greeting to everyone ,,

I had the sme problem that Adila Anbreen has (maximum cell skewness exceeds 0.98)

how can I use hexahedral elements for my 3D geometry؟؟
