#GPU Based Fluid Structure Interaction using Immersed Boundary Methods ##Author: Christopher Minar ##Advisor: Kyle Niemeyer ###Abstract:
Engineering applications often require fast, accurate solutions of fluid flow around freely moving bodies. The massive parallelism enabled by graphics processing unit (GPU) architecture enables high performance, offering a promising alternative to traditional solver acceleration via multicore central processing units (CPU). However, fully harnessing GPU parallelism requires specialized algorithms and computing strategies. This work modifies direct-forcing immersed boundary methods to model fluid-structure interaction and investigates this behavior on GPUs. I performed solver verification using lid-driven cavity flow, impulsively started flow over a cylinder, flow over a forced oscillating cylinder and vortex-induced vibration.
