Hollowed object - boundary issue
 

Hi guys

Using a simple cube for an external aerodynamics cases works perfectly of course, but everytime I am replacing it with a hollowed one, I am loosing all the boundaries descriptions in polymesh/boundary file except this hollowed cube one after reconstruction.

On the attached screenshot you can see that the hollowed cube is well captured, but there is no more inlet, outlet and so one.

Any idea of what's going on? Thanks.
