If you have been working with CFD or FEA individually, this is where you take the next step. This project gives you a complete understanding of Fluid Structure Interaction, from the core theory of how fluids and structures interact, to the different modeling approaches available in Ansys, to a full hands-on 1-way FSI simulation of a flow probe exposed to a high velocity flow of 100 meters per second. What makes this project valuable is the build-up. We do not jump straight into software. We first establish a clear understanding of when to use 1-way versus 2-way coupling, how Static Data Transfer and System Coupling differ, and what actually makes a simulation 2-way under the hood. Then we execute a complete simulation and get real structural stress and deformation results out of it. This is the first project in a three-part FSI series. The next project steps up to 2-way transient FSI of a hyperelastic flap with dynamic remeshing, followed by aeroelastic wing deflection as a real engineering use case.
