翼型计算的2D网格生成代码，学习和研究抛物和椭圆型网格生成算法(2D grid generation for computational fluid dynamics.Hyperbolic and elliptic grid generation available)

对比了基础dv-hop算法，和改进的2d-hyperbolic 方法，引进了权重因子，在很大程度上改进了定位精确度。(Compared with the basic DV hop algorithm and the improved 2D hyperbolic algorithm, the weight factor is introduced to improve the positioning accuracy to a large extent.)
