Fluid–Structure Interaction


Physics-based multiphysics coupling for free-surface and deformable systems

This research area develops robust and high-fidelity coupling strategies for free-surface flows and deformable structures. We focus on particle–structure interaction under impact, sloshing, and transient loading conditions, integrating meshfree and grid-based formulations for engineering-scale simulations.
