Over at TACC, Jorge Salazar writes that new supercomputer simulations are helping doctors improve the repair and replacement of heart valves. “New supercomputer models have come closer than ever to capturing the behavior of normal human heart valves and their replacements, according to recent studies by groups including scientists at the Institute for Computational Engineering and Sciences (ICES) at The University of Texas at Austin and the Department of Mechanical Engineering atIowa State University.”
