Abstract

Astrophysical simulations model phenomena that can't be fully reproduced terrestrially. Validation then requires carefully devising feasible experiments with the relevant physics. The authors describe validating simulations against experiments that probe fluid instabilities, nuclear burning, and radiation transport, and then discuss insights from - and the limitations of - these tests.
验证天体物理模拟代码
天体物理模拟模拟了无法在陆地上完全重现的现象。验证需要仔细设计可行的相关物理实验。作者描述了针对探测流体不稳定性、核燃烧和辐射传输的实验的验证模拟,然后讨论了这些测试的见解和局限性。
