Emphasis is placed on the understanding of basic principles, rather than on the details of individual numerical algorithms. The book covers all topics essential for students of elementary and intermediate courses on numerical methods in solid mechanics, and it also serves as a useful reference for researchers and other professionals.

With the advent of super computers during the last ten years, the numerical simulation of viscous fluid flows modeled by the Navier-Stokes equations is becoming a most useful tool in Aircraft and Engine Design.

In fact, compressible Navier-Stokes solvers tend to constitute the basic tools for many industrial applications occuring in the Author: Marie Odile Bristeau Roland Glowinski. This book provides the background and knowledge necessary to avoid these pitfalls, especially the most commonly used numerical methods employed in the solution of physical problems.

It offers an in-depth presentation of the numerical methods for scales from nano to macro in nine self-contained chapters with extensive problems and up-to-date. The main focus of this book is the transport mechanics of sediment particles coated with microbial biofilm, which is called bio-sediment.

The book also addresses the question of how to measure and simulate the considerable variation in the properties of natural sediment associated with microbial biofilm, ranging from the micro-scale surface morphology to the macro-scale sediment : Springer-Verlag Berlin Heidelberg.
