Isn't a streamfunction like a vectorfield? Shouldn't you be using
something like this (but then in 3D):

I don't understand. So you have coordinates (R,phi,z) which can be
easily transformed to (x,y,z). f,g and h aren't defining the
vectorfield are they? So what are they and how is your vectorfield
based upon them? Maybe I'm missing something obvious here...
