Filecombine
说明: 这是个人写的简单的文件合并工具,有如下特性:
1. 支持二进制和文本文件合并;
2. 可以自定义填充字节(默认为0);
3. 可以选择源文件的任意地址和任意数据长度(在源文件的数据范围之内);
4. 可以任意修改源文件数据在目标文件(合并或拆分)文件的地址范围;
5. 支持拆分源文件,但单次操作只支持一个源文件和一个目标文件;
6. 可以保存/加载文件拆分合并的配置数据,并于重复使用;(This is a simple file combine tool with the following characteristics:
1. Support binary and text file combine;
2. You can customize the padding byte (default is 0);
3. You can select any address of the source file and any data length (within the data range of the source file);
4. The source file data can be arbitrarily modified in the address range of the target file (combine or split) file;
5. Support split source files, but only one source file and one target file are supported in a single operation;
6. You can save/load the file to combine, split configuration data and reuse it;)

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

The program is not optimized for example, memory consumption is not optimized such as straight-edge boundary integral of the unit is still mining

drawMFC
一个简单的程序,可以绘制点、线、圆、方。可以保存成一定格式的图片文件。软件最大的问题是绘图基本在对应的鼠标事件里进行,而没有在paint方法里进行,可借鉴。(A simple program, you can draw points, lines, circles, square. Can be saved into a certain format image files. The biggest problem is the graphics software basic mouse events in the corresponding conduct, but not in the paint method in the conduct, we may learn.)
