Atomistic Computer Simulations: A Practical Guide

Many books explain the theory of atomistic computer simulations; this book teaches you how to run them

This introductory "how to" title enables readers to understand, plan, run, and analyze their own independent atomistic simulations, and decide which method to use and which questions to ask in their research project. It is written in a clear and precise language, focusing on a thorough understanding of the concepts behind the equations and how these are used in the simulations. As a result, readers will learn how to design the computational model and which parameters of the simulations are essential, as well as being able to assess whether the results are correct, find and correct errors, and extract the relevant information from the results. Finally, they will know which information needs to be included in their publications.

This book includes checklists for planning projects, analyzing output files, and for troubleshooting, as well as pseudo keywords and case studies.

“What a gem! This is a truly outstandingly useful book for anyone working in (or supervising students in) projects based around atomistic computer simulations . . . This book is a joy to read and will be of interest to specialists but also to anyone with a general interest in physics and indeed the history of science.”  (Contemporary Physics, 11 April 2014)
