本文介绍了有限元放电模型（FEDM）代码，该代码使用开源计算平台FEniCS（https：//fenicsproject. org）。基于FEniCS，FEDM代码利用有限元方法来求解偏微分方程。它扩展了FEniCS的功能，允许自动执行和完全耦合的流体泊松模型，包括任意数量的粒子平衡方程的数值解。使用精确解和基准测试的方法验证代码。基于物理的飞行时间实验的例子，一个积极的流光放电在大气压空气和低压辉光放电在氩气中被用作严格的测试用例的开发的建模代码，并说明其能力。代码的性能与商业软件包COMSOL Multiphysics®进行了比较，并获得了相当的并行加速。结果表明，FEDM实现的迭代求解器在高性能计算集群上表现特别好。
This paper introduces the finite element discharge modelling (FEDM) code, which was developed using the open-source computing platform FEniCS (https://fenicsproject. org). Building on FEniCS, the FEDM code utilises the finite element method to solve partial differential equations. It extends FEniCS with features that allow the automated implementation and numerical solution of fully coupled fluid-Poisson models including an arbitrary number of particle balance equations. The code is verified using the method of exact solutions and benchmarking. The physically based examples of a time-of-flight experiment, a positive streamer discharge in atmospheric-pressure air and a low-pressure glow discharge in argon are used as rigorous test cases for the developed modelling code and to illustrate its capabilities. The performance of the code is compared to the commercial software package COMSOL Multiphysics® and a comparable parallel speed-up is obtained. It is shown that the iterative solver implemented by FEDM performs particularly well on high-performance compute clusters.
