I see you always reccomend the use of HEX instead of TET, this is ofcourse true and the ideal situation is always using HEX mesh, but most of the geometries I encounter are way too complex for HEX meshing in 3D solid elements (different wall thickneses, crazy curved surfaces etc.), ...
I am running a CFX problem with laminar flow through a duct. The fluid flows through some fins in the middle of the duct. When I mesh with tet, for
