We study the evolution of two fiducial configurations for binary neutron stars using two different general relativistic hydrodynamics(GRHD), distributed adaptive mesh codes. One code, HAD, has for many years been used to study mergers of compact object binaries, while a new code, MHDuet, has been recently developed with the experience gained with the older one as well as several novel features for scalability improvements. As such, we examine the performance of each, placing particular focus on future requirements for the extraction of gravitational wave signatures of non-vacuum binaries.

在非真空合并中实现保真度和可扩展性

我们使用两种不同的广义相对论流体动力学 (GRHD)、分布式自适应网格代码来研究双中子星的两个基准配置的演化。一个代码 HAD 多年来一直用于研究紧凑对象二进制文件的合并，而最近开发了一种新代码 MHDuet，它利用旧代码获得的经验以及几个用于可伸缩性改进的新功能。因此，我们检查每个的性能，特别关注未来对非真空双星引力波特征提取的要求。
