非结构网格的粒子程序较少,Finite Element Particle in Cell (FEM-PIC) 这个网站介绍了有限元法粒子模拟,采用的是有限元的非结构网格。对于静电问题,非结构网格下的泊松方程求解需要采用有限元方法或者有限体积方法。我之前采用comsol和openfoam做过简单尝试,文章后面贴了我当时的总结。 现在我继续尝试基于OpenFOAM开发...
不过 上面说法也有一定问题,volScalarField其实包括两部分,即内部场和边界场。BField.internalField()就是返回BField的内部场,内部场变量个数等于模拟区域内单元个数;BField.boundaryField()返回BField的边界场,边界场的变量位于边界的每个单元面的中心。这些场都是由一些模板类定义的宏,vol场对应文件src/finiteVolume/...
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, ...
