Dear all,

I have been trying to mesh the propeller blade with periodic boundaries in ICEM. The problems are that I get around 6k elements with negative Determinant 3x3x3, and 1k of elements with angles lower than 9 deg, as the figures showed.
To fix those issues, I only know we can edit the edge and split it with the "spline" or "control point" method to increase the angle.

I wonder if someone can tell me how to improve Determinant 3x3x3.
