Control Volume for External Flows
 

I'm facing the following problem. I need to model a radio/control plane. For that I need to create a mesh around the plane. The question is: Which shape? How big?

Does anyone of you has any article or book where I can find some guidelines for that?

I was trying to get some guidelines published a few years ago by QNET-CFD, but the website is not working anymore.

Thanks.
