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 Last made a triangular element of the program, not curved edge unit is so easy to form a vortex in the cylinder behind the Program to curved edge quadrilateral element vortices appear Unit is the order of 8-node quadrilateral element node number is 15,263,748 which is the four corners of the points in turn Is 1234 and then the side of the midpoint of the number 5678. Time promote the use of Runge-Kutta method Numerical flux of the overall situation of Lax-Friedrichs, flux Still can not capture the shock wave did not do the reconstruction or artificial viscosity do it Zaifayici. The program is not optimized for example, memory consumption is not optimized such as straight-edge boundary integral of the unit is still mining Integral method to increase the amount of computation such as surface integral with a curved edge, the line integral using the Gauss- The Legendr)
