Default Skewness in ANSA not matching Fluent

I am having a problem where I have created a model from a 3D scan. I've cleaned up the model a lot and generated a volume mesh with prism layers. When I switch to "hidden" I see no elements with the title OFF (after changing fluent skewness to 0.85, and going through an iteration of fixing quality).

I then export to fluent and read in. I check quality and it says I have 450 elements with skewness above 0.85.

This seems to have baffled support. Anyone seen anything like this before?

Hi MachZero

Have in mind that Fluent Skewness (Equi-Volume skewness) applies only to tetras.
Your mesh however also contains prisms as you have created layers.
If you want to check their quality too, you should activate Fluent ANGLE in F11 window for solids.
Then you will also be calculating Fluent EquiAngular skewness which applies for pentas, hexas and pyramids.
Then I am sure ANSA will show you the violating prisms that Fluent is identifying.
Hope this helps
