标题： ANTARES -- A Numerical Tool for Astrophysical RESearch -- With applications to solar granulation

摘要： 我们讨论了ANTARES代码的一般设计，该代码旨在用于一维、二维和三维的恒星流体力学模拟中包含辐射转移和真实微观物理过程的仿真。然后我们比较了不同数值方法的质量。我们已经应用ANTARES以获得高分辨率的太阳对流胞模拟，我们对其进行描述和分析。为了获得高分辨率，我们将网格细化应用于主要由爆炸性对流胞占据的区域。由下沉气流生成的小直径（~100公里）强而快速旋转的涡旋管在对流胞边界附近上升到光球层，通常以弧形从下方进入光球层。它们在很大程度上对对流胞边界的湍流速度场做出贡献。 显示英文摘要

摘要： We discuss the general design of the ANTARES code which is intended for simulations in stellar hydrodynamics with radiative transfer and realistic microphysics in 1D, 2D and 3D. We then compare the quality of various numerical methods. We have applied ANTARES in order to obtain high resolution simulations of solar granulation which we describe and analyze. In order to obtain high resolution, we apply grid refinement to a region predominantly occupied by an exploding granule. Strong, rapidly rotating vortex tubes of small diameter (~100 km) generated by the downdrafts and ascending into the photosphere near the granule boundaries evolve, often entering the photosphere from below in an arclike fashion. They essentially contribute to the turbulent velocity field near the granule boundaries.
