Here we focus on high-fidelity simulations of pathological and medical device hemodynamics including stenotic flows, aneurysms, stent-grafts, mechanical heart valves and rotary blood pumps. Our novel multiblock immersed boundary method approach makes handling complex and moving geometries easy and allows us to use high-order numerical methods. Capturing unsteady vortical structures may reveal new insights into disease progression, device performance, and blood damage.
