Note that one of the symmetry plane domains and one of the pipe wall domains have three connectors on one of their edges. Go to the Create Domain menu and build the five remaining domains for the main pipe. You should now have created all of the domains for the main pipe surface and symmetry plane as shown in Figure 30. Now you are ready to create the grid block in the main pipe. Remember that one of the faces of this block is the pole domain you created earlier that runs down the axis of the pipe.
Face Pick the pole domain.
Save the Face Pick one of the plane of symmetry domains. Save the Face Pick the other plane of symmetry domain. Save the Face Pick one of the pipe end domains. Save the Face Pick the other pipe end domain. Save the Face Pick the three pipe wall domains and the pipe intersection domain.
