The use of scientific principles to design and build structures, machines and other things such as bridges, roads, buildings, and vehicles is known as engineering. It uses modeling and simulation as a substitute for the physical examination. This involves using a computer to calculate the results of a physical phenomenon. A mathematical model is built by a computer which contains all the parameters of the physical model and represents it virtually. Simulation is an imitation of the operation of a process and system. It is used in various contexts such as simulation of technology for the optimization of performance, safety engineering, testing and video games. This book discusses the fundamentals as well as modern approaches to modeling and simulation in engineering. It presents researches and studies performed by experts across the globe. This book will serve as a valuable source of reference for graduate and post graduate students.
