需求
- 寻找合适的边界条件
- 测试不同参数的影响
- 解决SF三角网格问题
python面向对象编程的基本原则
- 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)
- 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)
- 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
