Fluid-Structure Interaction Analysis of the Heart Valve and Lower Urinary Tract

The focus of this research is to investigate the fluid-structure interaction problem of a mechanical bileaflet heart valve to improve its design and to perform dynamic fluid-structure interaction analysis for the lower urinary tract to better understand the mechanisms of urinary incontinence problem. The research uses FEA and CFD software packages as well as the powerful supercomputers available at MSI. The goal of this project is to develop a real-time virtual reality system for medical device designers. The researchers want be able to provide plentiful information for designers by integrating CAD, FEA, and CFD components into a virtual-reality system. The high-resolution CFD simulation in the mechanical bileaflet valve research usually contains huge amounts of flow data, and the dynamic fluid-structure interaction analysis based on the subject-specific pelvic computational model in the urinary incontinence research requires large-scale memory and high-speed CPU support.
