1. Overview
We propose to develop advanced parallel geometric and numerical algorithms and software for
simulating complex flows with dynamic interfaces. The development of scalable, parallel high-
accuracy algorithms for simulating such flows poses enormous challenges, particularly on systems
with thousands of processors. We will use the resulting tools to simulate blood flow in artificial heart
devices. This application provides an excellent testbed for the methods we develop: simulation-
based artificial organ design is extremely computationally challenging and of critical societal
importance.
Flows with dynamic interfaces arise in manyfluid-solid and fluid-fluidinteraction problems, and are
among the most difficult computationalproblems in continuum mechanics. Examplesabound in the
aerospace, automotive, biomedical, chemical, marine, materials, and wind engineering sciences.
