Dear Openfoam community,
I am new to this amazing CFD tool, and have a (maybe) stupid question about paraFoam.

How can I display both boundary patches and internal field from an Openfoam calculation? For example pressure contours in a pipe from an icoFoam result together with the pipe surface (clipped, of course, so that it doesn't hide the contours).

Do I have to load the Openfoam source twice and in one source enable only the internal field, and in the other enable only the boundaries? I expect this will be very inefficient for large data sets. Is it possible to put a kind of T-piece into the pipeline, basically branching the Openfoam source so that I can work on the internal field in one branch and on the boundaries in the other branch?

I hope my question is more or less clear. If you think the answer is trivial, please give a short step-by-step explanation, because I couldn't find a satisfying solution.
