Fluid-Structure Interaction (FSI) occurs when a fluid flow deforms a structure which in return influences the flow field.
The significance of aeroelastic instabilities has increased substantially in the last few decades, particularly in the industry of aviation and turbomachinery. A continuous trend towards lightweight and cost-efficient design forces engineers to push the boundaries in the design phase with the risk of leading to vibratory stresses and, in the worst case, to vibratory failure. Cadence offers several approaches to predict fluid-structure interactions depending on:
• the direct coupling between the flow and the structural solvers,
• the use of the coupling server MpCCI, which manages the communication and the interpolation of coupling data between the fluid and structure solvers,
