Hi all,

I am working with bio-heat transfer simulation using chtMultiRegionSimpleFoam solver.

I want to implement kappa (thermal conductivity) as a function of temperature.

I did not have any idea related to variable thermal conductivity. So, I watched this beautiful video where the thermal conductivity as a function is explained.


Now, I would like to implement kappa as a variable parameter such that as the temperature is solved, it should solve kappa also. As of now, the thermo-physical properties is as follows:


      molWeight   0;

        kappa   0.51;

        Hf      0;
        Cp      3770;

        rho     1050;
Any leads towards a light on variable thermal conductivity in bioheat transfer equation will be appreciated.
