triangulation
- 这是一个关于曲面三角化的VC++程序,包括三角划分,图形逼近,改进曲面,选择内部点,辅助平面到三维空间,四边形等等功能。-This is a triangle on the surface of the VC procedures, including triangulation, graphics approximation, improving surface, the internal choice, supporting two-dimensional to three-dimensio

L1_vector
- 输入四个点,判断此四点是否可形成一个平行四边形。 程序中描述了一个抽象数据类型Vector2D,表示一个向量。具有(x,y)两个值。其本身具有减另一个向量(minus(Vector2D)),判断自身是否为零向量(iszero()),与另一个向量对应值y,x乘积之差(inner(Vector2D))。由于两个向量平行,则乘积之差x1*y2-x2*y1=0。点A,B,C,D四点组成平行四边形的条件是AB//CD,BC//DA且各个向量皆不为零向量。 首先声明四个向量。向量i获得值的方法是

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
