摘要：
GenASiS（通用天体物理模拟系统）是一个主要为在世界领先超级计算机上模拟核心坍缩超新星而开发的代码。本文是系列第二篇，记录了牛顿自引力流体动力学的能力，包括处理原子核和核物质（“重子物质”）的表格微观物理状态方程。通过计算椭球体引力势等对自引力进行测试。在多维计算中得出超新星爆炸的相关特性。
英文摘要：
GenASiS (General Astrophysical Simulation System) is a code being developed initially and primarily, though not exclusively, for the simulation of core-collapse supernovae on the world's leading capability supercomputers. This paper -- the second in a series -- documents capabilities for Newtonian self-gravitating fluid dynamics, including tabulated microphysical equations of state treating nuclei and nuclear matter (`baryonic matter'). Computation of the gravitational potential of a spheroid, and simulation of the gravitational collapse of dust and of an ideal fluid, provide tests of self-gravitation against known solutions. In multidimensional computations of the adiabatic collapse, bounce, and explosion of spherically symmetric pre-supernova progenitors -- which we propose become a standard benchmark for code comparisons -- we find that the explosions are prompt and remain spherically symmetric (as expected), with an average shock expansion speed and total kinetic energy that are inversely correlated with the progenitor mass at the onset of collapse and the compactness parameter.
