论文摘要
Oscar Buneman,Charles Birdsall,Roger W. Hockney和John Dawson在1950年代已经开发了粒子中的方法(PIC)方法,并在计算能力的进步中已经进一步开发了许多领域,例如天体物理,磁层以及太阳能等上的磁层以及太阳能以及最近的大气和Laser-plaser-Plaser-Plansicsics。目前,有15多个半公开PIC代码可用,我们在这篇评论中讨论。随着世界各地的高性能计算设施中可用的计算能力,它的应用已广泛增长。这些系统允许研究天体物理等离子体的各种主题,例如磁重新连接,脉冲星和黑洞磁层,非相对论性和相对论的冲击,相对论喷射和激光 - 播种物理学。我们回顾了许多天体物理现象,例如相对论喷射,不稳定性,磁重新连接,脉冲星以及激光 - 血浆物理学的PIC模拟(直到2021年),以强调模拟中涉及的物理学。最后,我们对与中子恒星,黑洞及其合并相关的喷气机的未来模拟进行了展望,并根据Petascale和Exascale计算来讨论PIC模拟的未来。
The Particle-In-Cell (PIC) method has been developed by Oscar Buneman, Charles Birdsall, Roger W. Hockney, and John Dawson in the 1950s and, with the advances of computing power, has been further developed for several fields such as astrophysical, magnetospheric as well as solar plasmas and recently also for atmospheric and laser-plasma physics. Currently more than 15 semi-public PIC codes are available which we discuss in this review. Its applications have grown extensively with increasing computing power available on high performance computing facilities around the world. These systems allow the study of various topics of astrophysical plasmas, such as magnetic reconnection, pulsars and black hole magnetosphere, non-relativistic and relativistic shocks, relativistic jets, and laser-plasma physics. We review a plethora of astrophysical phenomena such as relativistic jets, instabilities, magnetic reconnection, pulsars, as well as PIC simulations of laser-plasma physics (until 2021) emphasizing the physics involved in the simulations. Finally, we give an outlook of the future simulations of jets associated to neutron stars, black holes and their merging and discuss the future of PIC simulations in the light of petascale and exascale computing.
