how to check the quality of polyhedral mesh

krishnarajvvv

i used the polyhedral mesh to simulate solidification inside a cylindrical cavity. it shows a mesh quality of 0.71, is it sufficient ? how to check the quality of polyhedral mesh since the orthogonal quality value is inappropriate for such mesh. also what parameter is important for checking quality of such mesh.?

If you using Fluent, please check orthogonal quality.

The min orthogonal quality should be below 0.1 to proceed to solver. If it is less than 0.1 then please improve the mesh. 

First check the locations of the bad elements. Please see following video for the same.

Once you have locations, please check if you can improve mesh using different mesh sizing. Please see following video.

If this does not help, you may need to check if you can use pinch control or virtual topology.

If this does not help, please go to geometry and modify or simplify geometry at those locations in SpaceClaim.
