需求

    1. 寻找合适的边界条件
    1. 测试不同参数的影响
    1. 解决SF三角网格问题

python面向对象编程的基本原则

    1. 构想阶段——考虑步骤,不考虑实现(你能想到的事情,编程语言的库基本都帮你实现)
    1. 实施阶段——逐个完善各个函数的具体实现(易用、参数传递、加深考虑)
    1. 完善阶段——易读性、巧妙的实现方式(漂亮的代码是改出来的)

构想阶段

- 1. 影响边界条件的因素

cf: Effect of density boundary on the plasma solution including the mesh(Chaofeng Sang)

  • effect of core width
  • effect of sol width
  • effect of leakage
  • effect of decay length
  • application: leakage factor for the narrow-SOL

cf: I wishes to thank chen and daoyuan for fruitful discussion

  • feedback_chen
  • feedback_dao
  • inputfile_dao
  • mesh_GY Zheng (chen)
