Fea Fluid Dynamics

This is the most common "FEA fluid" application. The fluid pushes on a solid (e.g., a heart valve or airplane wing), and the solid bends back to change the fluid flow.

When fluid velocities increase, the convective term dominates over the viscous term. The dimensionless quantifies this relationship: This is the most common "FEA fluid" application
