I've been doing some joule heating simulations and I noticed something interesting/troubling. The results I get from the Joule Heating module differ from those that I get from using the Electric Currents and Heat Transfer modules in parallel. I've noticed this with the complex part I am investigating as well as with a very simple rod. The Joule Heating module simulations give temperatures that are roughly double those from the Electric Currents/Heat Transfer simulations, and the Electric Currents/Heat Transfer simulations are giving the results that closer to what is expected. Can anyone explain why this is? I would like to be able to explain why I am going with one set of results over another with something other than "because it seems more correct."
I've only been able to test this on version 4.0a.

be aware that there were a few formula errors (i.e missing factorss of 2) in the early v4.0 version, my suggestion is to use the latest version/patch, far more stable and less frustrating ;)

Good luck
