Dear friend tell more about your geometry and technique.if you have a 3d curve body you should divide it. for curve geometries using required stretch near for example walls caused to high skewness which result in small gap or negative volume.

1. check your coordinate: right-handed or left-handed.
2. check if any cell curve intersect with the opposite grid line in one cell, this often happens within boundary cells, when grid points deviate from the original geometry.
