<p>Comment (by Zach Etienne):</p>
<p>The main documentation (the IllinoisGRMHD paper <a data-is-external-link="true" href="https://arxiv.org/pdf/1501.07276.pdf" rel="nofollow">https://arxiv.org/pdf/1501.07276.pdf</a> ) says:</p>
<p>“… the current version supports only single gamma-law EOSs…”</p>
<p>Full support for the “hybrid equation of state” (of which piecewise polytrope is a limiting case) was incorporated into the NRPy+ version of IllinoisGRMHD, which is rather pedagogically documented in many Jupyter notebooks:<br />

<p>We proposed this version for inclusion in the Toolkit but it was rejected due to very minor backwards incompatibility.</p>
