icem cfd mesh method used

I just received a mesh generated using icem cfd and I am wondering if there is a way to know the method that was used to generate the mesh. It seems that the mesh was generated using patch conforming method, but now I want to know what kind of algorithm was used (delaunay or advancing front).
It is possible,?, Am I missing something?

There is no analytical method that I know of, but as an experienced ICEM CFD user, I could tell just by looking at a cross section.
By eye, Octree Tetra shows very regular aligned cubes cut into 12 tetras each. (looks like 4 in cross section).
Delaunay tetra is a simple fill and usually has a higher growth ratio.
Advancing front usually has a smoother transition... Maybe you could use the volume ratio diagnostic if you wanted this info in a numeric way.
But in the end, if you can't tell the difference, does the difference matter
I guess you could just regenerate the mesh with one of the methods and see if you get the same result.
Of course there are also a variety of methods that could have been used to generate the surface mesh.
