Level Set Methods for Fluid-Structure Interaction

This monograph is devoted to Eulerian models for fluid-structure interaction by applying the original point of view of level set methods.

In the last 15 years, Eulerian models have become popular tools for studying fluid-structure interaction problems. One major advantage compared to more conventional methods such as ALE methods is that they allow the use of a single grid and a single discretization method for the different media. Level set methods in addition provide a general framework to follow the fluid-solid interfaces, to represent the elastic stresses of solids, and to model the contact forces between solids. This book offers a combination of mathematical modeling, aspects of numerical analysis, elementary codes and numerical illustrations, providing the reader with insights into the applications and performance of these models. Assuming background at the level of a Master's degree, Level Set Methods for Fluid-Structure Interaction provides researchers in the fields of numerical analysis of PDEs, theoretical and computational mechanics with a basic reference on the topic. Its pedagogical style and organization make it particularly suitable for graduate students and young researchers.

A self-contained introduction covering both theoretical and numerical aspects Provides numerical illustrations of a variety of fluid-structure interaction problems Includes codes for hands-on experience of the methods in simple problems
