Abstract

We develop a new two level finite difference scheme for the 1D Pennes' bioheat equation. We further prove that the scheme is stable and convergent unconditionally. Numerical experiments for a skin heating model are conducted.


Key words: bioheat transfer, Pennes' equation, finite difference.
