FSI Fluid-Structure Interaction

FSI stands for Fluid Structure Interaction

The goal of Fluid Structure Interaction, FSI, is to model the effects of the coupling of both physics, fluid dynamics and structural dynamics. An structure can be deformed under the action of flow modifying the flow itself which alters the structure in a different way causing dynamic effects. These models allow for the identification of the representative magnitudes characterizing the phenomena and leading to its avoidance.

Fluid-structure modal analysis

Some of the jobs that can be carried out are:

  • Airfoil optimization accounting for these coupled effects, wings, etc. to avoid aeroelasticity phenomena
  • Load prediction upon deforming bodies as a function of the flow advance. Corresponding modal analysis.
  • Other coupling simulation involving different physics
