Steady state temperature in a circular bar with heat generation

Hi. I want to find the temperature at the center of a circular bar.

- Infinite length, or finite length with no end effects or axial heat flow
- Outside surface maintained at a fixed temperature
- Heat generated uniformly throughout the material
- Ignoring temperature dependence of material properties

This could represent a current carrying wire submerged in flowing water.

It's not homework. My attempt to solve it is using finite element analysis (FEA). But I want to confirm the result with a hand calculation. Also some quick formula or calculator would be fine. The actual numbers used don't really matter because I can adjust the FEA model to suit.

Ah it's OK. I managed to solve a simpler problem instead.
