Fiber coil sandwiched between two plates. Thermal analysis not giving the type of answer that makes sense.

(Ignoring the top plate for now)


- Fiber 60W/m

- Fiber is 1m in length

- Fiber outer diameter: 250um

- Bottom plate (copper) at a stable 55oC

- Assume no thermal contact resistance


Part attached.


I expect to see a heat pattern on the fiber and for it not to be so uniform on the top plate. I have obviously done something wrong but cannot find the mistake.
