论文摘要
PICFOAM是一种完全动力学的静电粒子中的求解器（PIC）求解器，包括蒙特卡洛碰撞（MCC），用于在OpenFOAM的开源框架中，用于非平衡等离子体研究。求解器的模块化设计基于OpenFOAM中使用的相同原理，通过允许用户在运行时和可扩展的方式选择不同的方法，从而使其具有很高的灵活性。采用有限体积方法的PIC方法的实现使其可以在一到三个维度中模拟任意几何形状。 OpenFOAM的Barycentric粒子跟踪有效地使用了基于拉格朗日粒子的描述到欧拉场的描述和向后描述的电荷和现场加权，而无需计算昂贵的粒子搜索算法。 PICFOAM还包括用于描述实际等离子体设备的开放电路边界模型。
picFoam is a fully kinetic electrostatic Particle-in-Cell(PIC) solver, including Monte Carlo Collisions(MCC), for non-equilibrium plasma research in the open-source framework of OpenFOAM. The solver's modular design, based on the same principles used in OpenFOAM, makes it highly flexible, by allowing the user to choose different methods at run time, and extendable, by building upon templated modular classes. The implementation of the PIC method employing the finite volume method, allows it to simulate on arbitrary geometries in one to three dimensions. OpenFOAM's barycentric particle tracking is used effectively to performe charge and field weighting from the Lagrangian particle based description to the Eulerian field description and backwards without computational expensive particle searching algorithm. picFoam also includes open and general circuit boundary models for the description of real plasma devices.
