Domain Heat Sources
The sum of the domain heat sources added by different physics features is available in the variable Qtot, which is the sum of:
•
Q’s, which are the heat sources added by the Heat Source (described for the Heat Transfer interface) and Electromagnetic Heating (described for the Joule Heating interface in the COMSOL Multiphysics Reference Manual) features.
•
Qmet, which is the metabolic heat source added by the Bioheat feature.
•
Qdmg, which is the cooling source added by the Irreversible Transformation feature.
•
Qr, which is the radiative heat source added by the Heat Transfer with Radiation in Participating Media, Heat Transfer with Radiation in Absorbing-Scattering Media, and Heat Transfer with Radiative Beam in Absorbing Media multiphysics features.
•
Qgeo, which is the geothermal heat source added by the Geothermal Heating feature.
In Bioheat, the out-of-plane (heat flux and radiation) and blood contributions are not added to Qtot because these are considered to be fluxes.
