TeraGrid Simulations of Blood Flow in Human Arterial Tree

We employ a hybrid approach to model interactions of blood flow in different regions of human cardiovascular network: using 3D detailed fluid dynamics within sites of interest such as artery bifurcations and a reduced set of 1D equations to model waveform coupling between sites of interest. Highly scalable algorithms enable us to conduct arterial tree simulations with realistic human artery geometries on the TeraGrid, the largest computational grid in the US. We conduct coupled cross-site computations over supercomputers distributed across the continent. The algorithms and some results will be presented.
