Euler_DG_Quadrilateral_2D
自己写了一个二维Euler方程的间断有限元程序
上次发了一个三角形单元的程序 因为不是曲边单元 所以在圆柱后面容易形成涡
现在把程序改为曲边四边形单元了 没有涡出现
单元是8节点四边形单元 节点编号顺序是 1 5 2 6 3 7 4 8 也就是四个角点依次
是1 2 3 4 然后是边的中点编号 5 6 7 8.
时间推进采用 Runge-Kutta 方法
数值通量采用全局Lax-Friedrichs通量
仍然不能捕捉激波 因为没有做重构或者加人工粘性 等这个做出来了 再发一次。
程序没有进行优化 比如说内存的消耗没有优化 比如直边单元的边界积分仍然采
用了曲边的积分方法 增加了计算量 比如面积分、线积分都是采用的是Gauss-
Legendre-Lobatto积分 积分精度会比一般的Gauss-Legendre积分精度低一阶 等
等问题。 二维的 纯属交流性质 就没有考虑这些问题 ^_^
如果物面全部是直边 那么只要改变一个参数N 就可以获得不同的计算精度 且具
有谱精度 因为单元的节点是Gauss-Legendre-Lobatto积分点。 其实就是谱元法
（物面是曲边的情况我不清楚是不是也可以通过提高基函数的阶数 也就是增加N
来提高计算精度）(Wrote a two-dimensional Euler equations with discontinuous finite element program

比Windows自带的高级一点的计算器，能将整个表达式输入，然后求值。
这个程序要求读者具备编译原理的一些知识。
(Advanced calculator than Windows built, the whole expression input can be then evaluated. This program requires the reader to have some knowledge of compiler theory.)
