Dear all,

I am unable to measure temperature of a surface on which sun rays are being deposited in the Geometrical Optic module/Heat Transfer in Solids.

My system is:
Sun rays hit an optical lens, and then these rays are deposited onto a surface of a collector (Cu-plate).

COMSOL Optic Manual Guide says use Ray Heating that automatically include 1. Geometrical Optics (gop) and 2. Heat Transfer in Solids interfaces for measuring the temperature rise at the surface for you. BUT this is not happening in my simulation!

When my rays hit the collector (Cu-plate), the results of Temperature come empty (same as the initial room temperature).

My Wall BC at Cu-plate is set to Wall - Freeze - Deposited Ray Power.


Please advise.
Thanks

Can you please update with the solution if your problem has been resolved.

Infrared thermometers can measure surface temperature without contact. This is useful for hot or hard-to-reach surfaces. However, depending on the conditions, there is a difference in error. I have not seen any updates on this issue.
