Chapter 5 CFD Solution Analysis—Essentials

5.1 INTRODUCTION

Analyzing a computational solution represents an integral part in the use of CFD. In Chapter 4, some basic discretization techniques are introduced to allow the reader to familiarize with common methodologies of converting the governing partial differential equations into a system of algebraic equations. This system of algebraic equations is subsequently solved through numerical methods to provide approximate solutions to the governing equations. It is these approximate solutions that we can interchangeably refer to as computational solutions.

In the context of CFD, some of the primary concerns regarding the computational solutions are whether the solution can be guaranteed to approach ...
