How to mesh a room with an auto hexa cartesian?
 

Hi!

In a room, e.g. there are several cubes and no strange objects, an air inlet and an air outlet. I wanna to know how to mesh such a simply room with a Hexa cartesian mesh?Theoretically, the room's cartesian mesh with different densities can be automatically generated in a unstructured way (such as in Icepak) However, I cannot find a auto way to achieve this, the body-fitted method still retain some uncartesian mesh (thus I guess I must use structured blocks divided by every characteristic line in inlet, outlet and indoor cube objects, is that right?)

I just wanna to know a very simply way to achieve this (such the attachment), thanks
