 September 23, 2010, 06:33 how hexahedral mesh is done #1 New Member   harry Join Date: Sep 2010 Posts: 4 Rep Power: 6 hello, i am very new to this field. i am working on centrifugal pump. i was told to to do hexahedral meshing of the pump. since it's casing, water passage and impellor are not simple geometry(i.e. with continuing changing cross section). wat can i do abt it.

you may have to use ICEM. You may find that it is hard ,even impossible to use GAMBIT to do hexahedral meshing for a complicated geometry

they are just two aspects of evaluations of the grid you mesh.you had better learn from the GAMBIT help
