Coupled CFD-FEA simulation of long-span bridges

The design of long-span bridges is dominated by considerations of aeroelastic instabilities. In recent years we have investigated the possibility of using computational fluid dynamics (CFD) fully-coupled to structural finite element analysis (FEA) to simulate the fluid-structure interaction around such structures. The first aim is to verify or otherwise such an approach.

I am now supervising Guido Morgenthal who is undertaking a PhD on the use of computational fluid dynamics applied to bridges, focusing upon the use of the Discrete Vortex Method and more traditional Finite Volume CFD approaches to this aeroelastic problem. Guido's research page should contain plenty of information about how this work is progressing.
