I am interesting to solve an inverse heat conduction problem in order to determine the thermal conductivity using Comsol.
The study area is a block and I have the six boundary values and 50 temperature measurements in the area. I suppose that there is not heat generation and temperature doesn’t change (steady-state).
I would like to ask you if the above problem (the determination of thermal conductivity) can be solved using Comsol.
Where can I find more information that will help me with the above problem?
Thank you in advance,
George

ideally you need the optoimisation module, but if you have only one constant variable you can manage without (less precise mostly still often quite OK) You define your measurement values, and your probe ploints and you create a an error variable eoing My_Error_value = sum of (Tmodel-Tmeasured)^2, then you define a global expression My_Material_k such that My_Error value is "0" or minimum
There is some examples for the HT controlled loop that work in a similar way (see model library)

Good luck
