c#等值线生成程序，自动划分三角形网格，生成等值线、等值面，生成shape文件。-c# contour generating program, divided into triangular mesh automatically generate contours, isosurfaces, generate shape files.

FDTD.m 程序包括程序相关变量的定义，网格的尺寸的划分，激励源的设置及基于FDTD的圆柱谐振腔迭代分析。其中通过改变空间离散度dr和采样点个数nmax，进行分析得出结论；且空间步长dt与dr有关，可得出空间步长对结果影响。-FDTD.m program includes the definition of program-related variables, set the meshing of size, the excitation source and the FDTD-based i

对于计算流体力学中的有限元求解问题，首先要划分网格，本程序针对某一种问题，提供了一个划分网格的方法。-For CFD finite element to solve the problem, we must first mesh, the program for a certain problem, a method of a meshing.
