Fluid Structure Interaction Analysis with Abaqus and FLUENT

Engineering problems that involve the coupled response of a flowing fluid and a deforming structure constitute a broad class referred to as fluid-structure interaction (FSI). The interaction can be mechanical, thermal, or both. Many important problems involve some form of FSI, but the coupling effect is often ignored because of a lack of readily available solution technology. To address this limitation, Dassault Systèmes SIMULIA Corp. and Fluent, Inc. have partnered to provide a coupled solution capability.
The co-simulation capability, available beginning in Abaqus Version 6.5, can be used in a wide variety of ap-plications such as thermal-stress prediction in exhaust manifolds, design of valves and rubber diaphragms that restrict fluid flow, micro-fluidics, in-vivo vascular flows, consumer goods design, and packaging applications. In this technology brief we present several problems from different industries that have been analyzed with the Abaqus and FLUENT FSI capability.
