COMSOL 6.2 - Bioheat Materials Library

Bioheat Materials Library

The Bioheat materials library contains materials used with the Heat Transfer Module’s Bioheat Transfer interface. The properties are given either as a constant value, as a piecewise linear function of the temperature, or as a polynomial approximation function of the temperature that provides a good agreement with the reference, as summarized in the table below. Also see References for the Bioheat Materials Library.
