FLUID-STRUCTURE INTERACTION.

Abstract

Computational methods for fluid-structure analysis are surveyed. Emphasis is placed on semi-discretization methods, such as finite element and finite difference methods. Appropriate mesh descriptions and time integration procedures for various classes of problems are discussed. The need for mesh partitions, where the fluid and structure are integrated by different methods, is indicated, and three types of mesh partitions are discussed: explicit-implicit, implicit-implicit and explicit with different time steps. Some examples are presented to illustrate the applicability of various methods.
