Accretion discs are a critical component in many astrophysical processes, from star and planet formation to supermassive black hole accretion.The dynamics of these discs is often studied in simplified form due to physical and geometrical complexities. In this project, efficient and accurate numerical simulation methods will be used on high performance computing facilities to make progress. Specifically assumptions made in previous works relating to the symmetry or underlying physics of the accretion process will be relaxed. These simulations will be motivated by the latest developments in observational astrophysics, and yield potential explanations for observed effects and possibly predict what will be see by new missions.

吸积盘是许多天体物理过程的关键组成部分，从恒星和行星的形成到超大质量黑洞吸积。由于物理和几何的复杂性，这些吸积盘的动力学通常以简化的形式进行研究。在该项目中，将在高性能计算设施上使用高效、准确的数值模拟方法来取得进展。具体来说，之前的工作中所做的有关吸积过程的对称性或基础物理的假设将被放宽。这些模拟将受到观测天体物理学最新发展的推动，并对观测到的效应产生潜在的解释，并可能预测新任务将看到的情况。
