COURSE DESCRIPTION

Numerical methods are extremely powerful problem solving tools .These tools are capable of handling large system of equations, nonlinearities and complicated geometries that are not uncommon in engineering practice and that are often impossible to solve analytically. Numerical methods are an efficient vehicle for learning to use computer.  Numerical solution of differential equations (Ordinary as well as Partial), that are often encountered when a dynamic system is modeled, is explained with special emphasis on standard equations such as heat equation, wave equation and Laplace equation. The practice session in computer Lab gives students an opportunity to learn the development of the code in C/C++ for implementation of these methods on a variety of problems.

COURSE OBJECTIVES

To enhance problem solving skills of engineering students using a powerful problem solving tool namely numerical methods.
