I am trying to learn how to use Pointwise for 3D meshing and I have encountered some problems when it comes to selecting boundary conditions.

The mesh I am playing with at the moment is the PipeInACube which is one of the tutorials that come with the software.

When selecting BC, I would like to give the pipe inside the cube a wall condition. However, selecting those two domains that make up the pipe is impossible... And looking in "List, Domains" those two domains are also greyed out...

Why is this? And how should I go about setting BC for these two domains?

Thanks!
