CS 778 Numerical Solution of Partial Differential Equations



Objectives

This course studies basic methods for the numerical solution of partial differential equations. Emphasis is placed on regarding the discretized algebraic equations as discrete models of the system being studied. Example applications are drawn from: pollutant transport, computational fluid dynamics, computational finance, simulation of optical transmission lines.
