Negative Determinant
I've exported a mesh generated in Ansys meshing to the ICEM Input File(.prj) format.

Then I imported it into ICEMCFD. When I checked the determinant of the imported mesh in ICEMCFD, I found it to be a negative value.

Usually within workbench, I check the orthogonal quality, skewness and Minimum corner angle for the mesh and I found them good -

Orthogonal quality - 0.15
Skewness - 0.93
Minimum corner angle - 60 to 162 [deg.]

But the problem is with the negative determinant which I checked in ICEM after importing the mesh there.

Could some one please clarify this

Also is there a way to check the "equivolume skewness" in ICEMCFD I mean I'm not sure if the metric "equiangle skewness" of ICEM is in comparison with the skewness measure of Fluent.
