3-D Heat Equation Numerical Solution

Solution to the three-dimensional heat equation using alternating direction implicit (ADI) method

This function solves the three-dimensional Pennes Bioheat Transfer (BHT) equation in a homogeneous medium using Alternating Direction Implicit (ADI) method. The code has been developed for High-Intensity Focused Ultrasound (HIFU) treatments in tissue, but it can be applied to other heating problems as well. If desired, the solution takes into account the perfusion rate, thermal conductivity and specific heat capacity of tissue.
