Accurately Simulate Fluid-Structure Interaction to Ensure Product Safety and Reliability

Today’s products are subject to multiple interactions, one being the interaction of fluid dynamics and structural mechanics (fluid–structure interaction, or FSI). To have confidence in your products, you need to understand how the fluid and structure will impact each other. Whether you are analyzing small deformations in a piping system due to conjugate heat transfer (CHT) or predicting blade flutter in a gas turbine, FSI simulation is necessary to capture these effects. The results of failing to understand how fluids and structures interact with each other in detail can span from small, bothersome noises all the way to complete product failure.

This application brief defines fluid–structure interaction and the problems it can cause with your products. It describes the benefits of using different computing methods depending on the complexity and sensitivity of the interaction.
