Hi all,
What are the differences between the old snappyHexMesh (OF 1.7) and the the new one (OF 2.1). I meshed the same geometry with both versions, using the same dictionary and obtaining different mesh:

snappy of OF 2.1.0

Mesh stats
points: 5756460

polyhedra: 0

snappy on OF 1.7.1

The total number of cells is the same but in OF 1.7.1 i have only hexa (some cells were not exactly hex, but they were a little bit distorted) while in OF 2.1 i got also some prisms cells. Since i think that working with hex is always better how can i reproduce the same hex-mesh on OF 2.1? How can I avoid prisms?

thanks
