Hi, I'm new to the forums, and while I've come here for tips I've never had something that I've gotten really stuck on before, but now I'm at that point, so I figured I'd sign up.
I'll simplify the setup. A cylinder made of graphite is held at room temperature at the top and bottom, and an applied voltage or current is applied at the top. The joule heating then raises the temperature inside of the cylinder. There is also radiative heat loss on the outside of the cylinder.
So using this setup I'm getting the correct temperature distribution, just not in the correct time. It should take a few minutes for the system to reach steady state, but it's reaching steady state in under a second. I've tried all sorts of things, but it always reaches steady state way too quickly. Thanks in advance.
