Fluid-Structure Interaction (FSI)
Fluid-structure interaction (FSI) refers to the relationship between a deforming structure and adjacent fluid flow – either internal or external – which can be important in the design of many product and processes, from high performance valves and medical equipment to aerofoils and tall buildings. By coupling structural FEA and CFD solutions, simulation can assist at both the concept phase and when minimising the number of expensive prototype tests.
If the deflection of the structure does not sigificantly influence the fluid flow, a ‘one-way’ procedure allows the pressure and temperature predictions from a CFD model to act as boundary conditions for a structural analysis. In other cases, the FEA and CFD solvers need to be ‘two-way’ coupled until equilibrium between the fluid and structural behaviour is reached.
Wilde provides the leading FSI software solutions within the integrated ANSYS Workbench environment, together with practical experience through our combined CFD and FEA consulting and training teams.
