Named selection for internal surfaces in the domain
I want to simulate the flow over an ROV and I have a problem. I drew the ROV on solidworks then I drew the domain and subtracted the ROV from the domain, so now I have the domain with a cavity inside which is the shape of the ROV. I imported this geometry into CFX. The problem is that I want to select the ROV surfaces to define them as Named Selection but I don't know how to do so because they are unreachable !!
I need your help please
Thanks in advance
it is better to do it during meshing process...
