频率域有限体积波场模拟，可用于三角形不规则网格，较有限差分速度更快。-Frequency domain finite volume wave field simulation can be used for irregular triangular grid, faster than the finite difference.

采用SIMPLE算法对方腔驱动流进行模拟，采用交错网格和正交结构网格，对流项采用三阶quick格式，粘性项采用中心差分格式。RE数为100到1000的计算结果非常符合。-Use the SIMPLE to solve the cavity_drive proplem with the third-precise quick scheme for the convection item.the result is with good agreement .
