face-handedness and non-convex cells in Mesh
 

Hello All

I am using ICEM CFD 11

I created a tetra mesh which looks like cake slice (A 3 D Sector) . I defined the side walls of this cake slice( sector) as rotational periodic in FLUENT. It in fact created them as periodic.I can see the as grid interfaces from Grid---> grid-Interfaces

When GRID check happens FLUENT reports face handedness and possibly non convex cells in the mesh. So i tried to correct the mesh again in ICEM 11, but even improving the skewness up to 0.4 I still get the same face handedness in FLUENT when I read the grid.

My work demands to take these bad/skewed cells away from the mesh. So

1. How can I delete them or refine them using ICEM 11?
2. How to see or locate where these face-handed/non-convex cells in FLUENT and/or ICEM?

i tried much but of no result.....thanks for any suggestion from you
