[cfd^2]

Hi,

I have two domains, one inside other. I need to assign different materials to each one, so I declared different names to them when I created the geometry in designmodeler. When I open the model in Fluent I see two different BC for each surface of the interior domain. I eventually saw that if I gave the same name to the two domains in designmodeler this issue disappears and there is only one BC for each surface. But, since I need different materials it does not match my goals. I would like to know if there is any problem when duplicate BC are obtained... Moreover, I need to know if I have to setup the same conditions for each duplicated BC.

Regards.
