My favorite way is to add an ExplicitSystem named "auxiliary" or "post" to my EquationsSystem... then add all of the variables I want to calculate through postprocessing to that system. Then, when I'm postprocessing, I fill up the values in that auxiliary system. Finally, when you use GTKIO or whatever to write out the EquationsSystem those variables will automagically come out!
This keeps those variables separate from the linear system I'm solving (keeps them out of the matrix / solution / rhs vectors).
