This project aims to develop numerical methods for complex magnetohydrodynamic simulations able to handle sharp and dynamically evolving inhomogeneities, spherical geometries, and dramatic variations in density and wave speed across the simulation domain. The project plans to develop these methods within the context of solar wave processes, which are fundamental to the transfer of energy from the sun’s interior to its outer atmosphere, to the acceleration of the solar wind that rushes past the Earth continually, and to solar activity in general. This would provide the best available modelling of how the sun's atmosphere works, with direct implications for how the Earth's space environment is determined by solar storms and eruptions.

该项目旨在开发复杂磁流体动力学模拟的数值方法，能够处理急剧和动态演变的不均匀性，球形几何形状，以及整个模拟域中密度和波速的急剧变化。该项目计划在太阳波过程的范围内发展这些方法，太阳波过程对于能量从太阳内部向其外层大气的转移、对于不断掠过地球的太阳风的加速以及对于一般的太阳活动都是至关重要的。这将提供关于太阳大气层如何运作的现有最佳模型，直接影响到太阳风暴和爆发如何决定地球空间环境。
