Description
This book is intended for undergraduate and postgraduate students studying computational techniques. The book is application oriented as well as code-development oriented. It is focused towards inverse design and optimization methods. Emphasis is placed on efficient algorithms development and parallel computing. While Chapter 1 is introductory about the flow physics, Chapter 2 is about discretization of domains and stability of marching schemes. Chapter 3 describes the finite difference discretization, numerical features of schemes including issues related to conservative smoothing and implicit nature of unsteady problems. Chapter 4 is about structured and unstructured grid generation methodologies including surface grid generation.
