Advanced FSI Technology: ANSYS MFX Multi-field Solver - Technical Brief

Fluid Structure Interaction (FSI) occurs when fluid flow generates forces on a solid structure, causing it to deform and potentially perturb the initial fluid flow. This type of interaction causes the deformation of an aircraft wing during flight, for example, or the vibration of a civil engineering structure due to airflow. Fluid Structure Interaction also commonly includes other interactions, such as heat transfer, between fluids and solids.
