polyhedral mesh shown by tecplot as tetra..
 

Hello All,
I am using openfoam adn the mesh generated using polydualmesh is viewd both in parafoam (use VTKpolyhedron activated) and in tecplot... When viewing midslice..I get expected mesh view in parafoam and not in tecplot. I would like to use tecplot for post processing. Could anyone tell me the reason for such a behaviour.

Steps followed in tecplot:
LOad controldict (openfoam)
Switched on slice


(when viewed as whole volume the tecplot also shows polyhedral mesh but not in cut view)

(The simulation is : flow over a sphere in a cube box)
