Hello everyone I need to implement Pennes' Bio-heat transfer in comsol but cannot use the module that comes with comsol. I am thinking that using weak contributions is a good way. Does anyone know how to implement Pennes' Bio-heat transfer with weak contributions or other ways?

Hello Yuxiang,

While you could use a weak contribution, an easier solution is to simply add a volumetric heat source in the heat transfer in solids interface to account for the blood perfusion and metabolism term of Pennes equation.

Best regards,

Jeff
