For +instance, rectangular Cartesian grids are useful for the region directly +covering the central source (such as a binary neutron star system), but +spherical grids are more efficient in the far-away region, e.g. the +gravitational wave zone. Combining the different grid shapes can offer +significant performance/accuracy benefits. The multipatch implementation in +GRHydro is based on overlapping grids where ghost data between patches is +exchanged via high-order Lagrange interpolation polynomials for spacetime +variables, and second-order essentially non-oscillatory (ENO) interpolation for +fluid variables that may contain shocks and other discontinuities. I describe +the changes that were introduced to make GRHydro compatible with multipatch +grids. In addition, I also briefly describe the implementation of +cell-centered adaptive mesh-refinement and refluxing, a technique of ensuring +numerical flux conservation at mesh refinement boundaries (corresponding to +conservation of mass, energy, and momentum in the absence of gravity). I +finally show the performance of the new updates to GRHydro by a number of test +problems: (perturbed) TOV star, stellar collapse, and binary neutron star +coalescence. +</p> + +<h3>Presenter: Christian Reisswig</h3> +<img src="reisswig-new-s.jpg" width="20%" align="right" alt="Christian Reisswig"> +<p> + NASA Einstein Postdoctoral Fellow in Theoretical Astrophysics at the <a + href="http://www.tapir.caltech.edu/">Theoretical Astrophysics (TAPIR) group</a> + at the <a href="http://www.caltech.edu/">California Institute of Technology</a> +<p> + +<p>Research interests: +I am interested in the modeling of gravitationally radiating sources such as +coalescing compact binaries and collapsing stellar cores using numerical +relativity.
