<p>We (the authors of GiRaFFE) hereby request that GiRaFFE be added to the Einstein Toolkit. In short, GiRaFFE is the first open source, dynamical-spacetime code for modeling plasma flows in general relativistic force-free electrodynamics (GRFFE). It will be the best code in the Toolkit for modeling black hole and neutron star magnetospheres, as these magnetically-dominated regions are best modeled numerically by a GRFFE code (GRMHD codes break down when modeling very highly magnetized plasmas).</p>

<p>Here is the original release announcement to the mailing list, including link to the code release paper:</p>
<p>We are pleased to announce the public release of GiRaFFE, an open-source General Relativistic Force-Free Electrodynamics (GRFFE) code for dynamical spacetimes.</p>

<p>Our code release paper--including a full description of the GiRaFFE code, a discussion of potential applications of GiRaFFE, and code validation test results--has been uploaded to the arXiv: <a href="https://arxiv.org/abs/1704.00599" rel="nofollow" class="ap-connect-link">https://arxiv.org/abs/1704.00599</a> .</p>
<h2 id="markdown-header--executive-summary-">-= Executive Summary =-</h2>
<p>GiRaFFE adopts the strategy pioneered by McKinney [1] and modified by Paschalidis and Shapiro [2] to convert a general relativistic magnetohydrodynamic (GRMHD) code into a GRFFE code. In short, GiRaFFE exists as an extensive modification to IllinoisGRMHD [3]. Both GiRaFFE and IllinoisGRMHD leverage the Einstein Toolkit’s highly-scalable infrastructure [4,5] to make possible large-scale simulations of magnetized plasmas in strong, dynamical spacetimes on adaptive-mesh re
