论文摘要
我们通过泄漏方案为Illinoisgrmhd添加了对现实，微物理，有限的状态（EOS）和中微子物理学的支持，这是Einstein工具包中动态空间的开源GRMHD代码。这些新功能由两个新的，基于NRPY+的代码提供：NRPYEOS，它执行了高效的EOS表格查找和插值以及NRPyLeakage，它在爱因斯坦工具包中实现了一种新的，具有AMR的中性中微子泄漏方案。我们进行了一系列剧烈的验证测试，这些测试证明了这些新代码的鲁棒性，尤其是在地毯提供的笛卡尔AMR网格上。此外，我们显示了单个未磁性中子星和磁化二元中子星星合并的完全动力学GRMHD模拟的结果。这种新版本的Illinoisgrmhd以及Nrpyeos和Nrpyleakage在Jupyter Notebook和完全开源的教学上进行了教学记录。这些代码将被提议包含在即将出版的爱因斯坦工具包中。
We have added support for realistic, microphysical, finite-temperature equations of state (EOS) and neutrino physics via a leakage scheme to IllinoisGRMHD, an open-source GRMHD code for dynamical spacetimes in the Einstein Toolkit. These new features are provided by two new, NRPy+-based codes: NRPyEOS, which performs highly efficient EOS table lookups and interpolations, and NRPyLeakage, which implements a new, AMR-capable neutrino leakage scheme in the Einstein Toolkit. We have performed a series of strenuous validation tests that demonstrate the robustness of these new codes, particularly on the Cartesian AMR grids provided by Carpet. Furthermore, we show results from fully dynamical GRMHD simulations of single unmagnetized neutron stars, and magnetized binary neutron star mergers. This new version of IllinoisGRMHD, as well as NRPyEOS and NRPyLeakage, is pedagogically documented in Jupyter notebooks and fully open source. The codes will be proposed for inclusion in an upcoming version of the Einstein Toolkit.
