Astrophysical fluid flow studies often encompass a wide range of physical processes to account for the complexity of the system under consideration. In addition to gravity, a proper treatment of thermodynamic processes via continuum radiation transport and/or photoionization is becoming the state of the art. We present a major update of our continuum radiation transport module, Makemake, and a newly developed module for photoionization, Sedna, coupled to the magnetohydrodynamics code PLUTO. These extensions are currently not publicly available; access can be granted on a case-by-case basis. We explain the theoretical background of the equations solved, elaborate on the numerical layout, and present a comprehensive test suite for radiation–ionization hydrodynamics. The grid-based radiation and ionization modules support static one-dimensional, two-dimensional, and three-dimensional grids in Cartesian, cylindrical, and spherical coordinates. Each module splits the radiation field ...

Makemake + Sedna:天体牛顿流体动力学的连续辐射传输和光电离框架

天体流体流动研究通常包含广泛的物理过程,以考虑所考虑系统的复杂性。除了重力以外,通过连续辐射传输和/或光电离对热力学过程的适当处理也成为了现有技术。我们介绍了我们的连续辐射传输模块Makemake的重大更新,以及一个新开发的光电离模块Sedna,并结合了磁流体动力学代码PLUTO。这些扩展名目前不公开;可以逐案授予访问权限。我们解释了所求解方程的理论背景,阐述了数值布局,并提出了用于辐射电离流体动力学的综合测试套件。基于网格的辐射和电离模块支持静态一维,直角坐标,圆柱坐标和球形坐标的二维和三维网格。每个模块将辐射场分开...
