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.
