中文说明：
墙角在对流边界情况下的温度场模拟计算程序。用户输入墙角两侧的流体主流温度，对流换热表面传热系数，设定墙角以及计算网格尺寸后，程序可以通过迭代求解墙体的温度场并以矩阵和三维图像的形式输出。
English Description：
The temperature field simulation program of wall corner in the case of convective boundary. After inputting the mainstream temperature of the fluid on both sides of the wall corner, the heat transfer coefficient of the convective heat transfer surface, setting the wall corner and calculating the grid size, the program can solve the temperature field of the wall iteratively and output it in the form of matrix and three-dimensional image
