论文摘要
我们介绍了一般性的多元化数值（GMUNU）代码的更新，这是一种并行的，多维的曲线性，一般的相对论磁性水力动力学代码，具有有效的非线性细胞中心中心的多层多裂（CCMG）椭圆求解器，完全与基于有效的Edective motect condective motective motective motections couptive MoteStive moteme。 Currently, Gmunu is able to solve the elliptic metric equations in the conformally flat condition (CFC) approximation with the multigrid approach and the equations of ideal general-relativistic magnetohydrodynamics by means of high-resolution shock-capturing finite volume method with reference-metric formularise multi-dimensionally in cartesian, cylindrical or spherical geometries.为了确保在进化过程中缺乏磁单孔，我们通过使用Multigrid求解器开发了一种椭圆形散射清洁方法。在本文中，我们介绍了我们代码GMUNU的方法，完整的演变方程和实施细节，其属性和性能以及在某些基准和具有挑战性的相对论磁性水力动力学问题中。
We present an update of the General-relativistic multigrid numerical (Gmunu) code, a parallelized, multi-dimensional curvilinear, general relativistic magnetohydrodynamics code with an efficient non-linear cell-centred multigrid (CCMG) elliptic solver, which is fully coupled with an efficient block-based adaptive mesh refinement modules. Currently, Gmunu is able to solve the elliptic metric equations in the conformally flat condition (CFC) approximation with the multigrid approach and the equations of ideal general-relativistic magnetohydrodynamics by means of high-resolution shock-capturing finite volume method with reference-metric formularise multi-dimensionally in cartesian, cylindrical or spherical geometries. To guarantee the absence of magnetic monopoles during the evolution, we have developed an elliptical divergence cleaning method by using multigrid solver. In this paper, we present the methodology, full evolution equations and implementation details of our code Gmunu and its properties and performance in some benchmarking and challenging relativistic magnetohydrodynamics problems.
