Fiber coil sandwiched between two plates. Thermal dissipation from the fiber. Thermal analysis not giving the type of answer that makes sense - should see a heat pattern on the metalwork / fiber.

- Fiber 60W/m

- Fiber is 1m in length

- Fiber outer diameter: 250um

- Bottom plate (copper) at a stable 55oC

- Assume no thermal contact resistance
