用Fortran编写的非线性优化软件，具有一定的智能搜索功能(used in Fortran program)

说明：  顶盖驱动流是不可压缩黏性的典型流动，可以用来检验各种数值算法计算精度和可靠性，目前尚不能求得它的解析解。基于Fortran 编程，采用 SIMPLE 算法求解二维方腔流动，得到流动达到稳定状态时各物理量的分布。(Lid-driven cavity flow is an incompressible viscous flow, which can be used to test the accuracy and reliability of various numerical algorithms. In this paper, based on the Fortran programming, SIMPLE algorithm was used to solve the lid-driven cavity flow. The distribution of physical quantities in the stable state was obtained.)
