I'm trying to get the steady-state heat flux out of a simple thermal model: a cylindrical wire with one end at 4K and the other at 300K (in vacuum and ignoring radiation so the sides can be treated as isolated). Eventually I'll want to put in the temperature-dependent thermal conductivity but for now I want to model something I can also solve analytically before adding the real complexity.
Things I've looked at so far, without finding the right combination of parameters/commands:

Get steady state heat flux out of a thermal model
Re: Get steady state heat flux out of a thermal model
Hi,
in a nutshell:
* make geometry
* mesh
* import mesh in ElmerGUI
* steady state simulation
* output file with extension .vtu
* Heat equation
* Boundary conditions: one end at 300 K, one at 4 K
* Initial condition: choose a start temperature
* post-processing with ParaView
HTH,
Matthias

that's different to what I've found so far, and no more intuitive. Is this the sort of thing you mean: https://www.simscale.com/forum/t/determ ... ow-w/34599 because from there I'll need to do quite a lot of further digging?

Hi,
let's take it step by step.
Do you have a geometry? In which format? Which meshing tool are you going to use?
