Fluid Structure Interaction

Welcome to the Fluid Structure Interaction toolbox

Fluid Structure Interaction (FSI) is a toolbox for the simulation of fluid-structure interaction problems. It is based on the partitioned approach, where the fluid and the structure are solved separately and the coupling is performed by exchanging the forces between the two solvers. The fluid solver is based on the Navier-Stokes equations, while the structure solver is based on the equations of elasticity. The coupling is performed using different schemes (explicit, semi-implicit) and the Arbitrary Lagrangian Eulerian mapping.

1. FSI Toolbox

We present the FSI toolbox interface. The fluid configuration is documented in the CFD Toolbox and the structure configuration is documented in the CSM Toolbox. There remains to document the coupling strategies between the fluid and the structure.
