Abstract

We present Pantera, an open-source, parallel, particle-based code for the simulation of rarefied gases and plasmas. The code uses the Particle-in-Cell (PIC) method for the solution of ionized flows in the electrostatic approximation, coupled to the Direct Simulation Monte Carlo (DSMC) method for particle–particle interactions, and Monte Carlo Collisions (MCC) technique for the interaction of particles with a fixed background. It uses unstructured grids, which allows for the representation of complex geometries. Various models are available for elastic collisions, reactions, and gas–surface interaction. Semi- and fully-implicit, energy-conserving PIC schemes are available, as well as a Boltzmann-fluid model for electrons, to improve numerical stability and speed up the simulations. The code is designed to be easily understandable and extensible to include new models and algorithms for aerospace applications and beyond.

Pantera：用于模拟稀薄气体和等离子体的pic - mc - dsmc软件

我们提出Pantera，一个开源的，并行的，基于粒子的代码，用于模拟稀薄气体和等离子体。该代码使用单元内粒子（PIC）方法在静电近似中解决电离流，耦合到粒子-粒子相互作用的直接模拟蒙特卡罗（DSMC）方法，以及具有固定背景的粒子相互作用的蒙特卡罗碰撞（MCC）技术。它使用非结构化网格，允许表示复杂的几何形状。各种模型可用于弹性碰撞，反应和气体表面相互作用。半隐式和全隐式节能PIC方案，以及电子的玻尔兹曼流体模型，可以提高数值稳定性并加快模拟速度。代码被设计为易于理解和扩展，以包括航空航天应用和其他应用的新模型和算法。

期刊介绍： SoftwareX aims to acknowledge the impact of software on today''s research practice, and on new scientific discoveries in almost all research domains. SoftwareX also aims to stress the importance of the software developers who are, in part, responsible for this impact. To this end, SoftwareX aims to support publication of research software in such a way that: The software is given a stamp of scientific relevance, and provided with a peer-reviewed recognition of scientific impact; The software developers are given the credits they deserve; The software is citable, allowing traditional metrics of scientific excellence to apply; The academic career paths of software developers are supported rather than hindered; The software is publicly available for inspection, validation, and re-use. Above all, SoftwareX aims to inform researchers about software applications, tools and libraries with a (proven) potential to impact the process of scientific discovery in various domains. The journal is multidisciplinary and accepts submissions from within and across subject domains such as those represented within the broad thematic areas below: Mathematical and Physical Sciences; Environmental Sciences; Medical and Biological Sciences; Humanities, Arts and Social Sciences. Originating from these broad thematic areas, the journal also welcomes submissions of software that works in cross cutting thematic areas, such as citizen science, cybersecurity, digital economy, energy, global resource stewardship, health and wellbeing, etcetera. SoftwareX specifically aims to accept submissions representing domain-independent software that may impact more than one research domain.
