The Method of Weighted Residuals and Variational Principles describes variational principles, including how to find them and how to use them to construct error bounds and create stationary principles. The book also illustrates how to use simple methods to find approximate solutions, shows how to use the finite element method for more complex problems, and provides detailed information on error bounds.
Problem sets make this book ideal for self-study or as a course text.
Audience: Engineers and scientists who need to solve differential equations and want to have a deeper understanding of some of the available methods, particularly in fluid mechanics, will find this book useful. Instructors of graduate-level courses that cover approximate and numerical solutions can use it as a textbook.
