Dear all,

I would like to know if there is any way I can improve the quality of the cells in the corners of the inner block of the O-grid.

I am creating a mesh with an annular inlet region using O-grid and even though the mesh seems to be ok (pictures 1&2), there are few cells which are very distorted as seen in picture 3 (these cells have determinant 3x3x3 as 0.26 << 0.3).

Is there any way these cells can be smoothed or improved? Is there any other tool in ICEM to generate this type of meshes?

Thank you very much,
