FEYNMAN_KAC_3D
PDE Solution by Feynman-Kac Algorithm


FEYNMAN_KAC_3D is a FORTRAN90 program which demonstrates the use of the Feynman-Kac algorithm to solve Poisson's equation in a 3D ellipsoid by averaging stochastic paths to the boundary.

The program is intended as a simple demonstration of the method. The main purpose is to have a version that runs sequentially, so that it can be compared to versions which have been enhanced using parallel programming techniques.
