关于Gridgen生成多段翼型的单块结构网格的疑问

010210623

在Gridgen官方网站上看到了，用Gridgen可以生成多段翼型的单块结构网格，好像很简便，但是对于网站上的叙述，小弟实在无法领悟，还请高人指点！请大家帮帮忙，小弟万分感谢！原文如下
Multi-Element Airfoil

[1998] Gridgen's hyperbolic solver was used to create this single-zone structured quad-cell grid for a multi-element airfoil. After importing the geometry definition, the user simply defined grid point locations along the perimeter of each element, linked them all together, and invoked the hyperbolic solver which automatically marched the grid outward from the airfoil surface to the farfield. The resulting grid is orthogonal and clustered toward the airfoil surface and grows smoothly outward without any crossed cells. Additionally, the topology is extremely simple - a single zone.

This airfoil, data for which was published in AGARD-AR-303, (1994), is typical of the type the high lift aerofoil geometry used in commercial aircraft wing design.
