Airfoils

[1998] Constructing simple grids for airfoils shouldn't be a topological exercise - and it isn't with Gridgen's hyperbolic grid technique. Creating the grids shown below is simply a matter of specifying your grid point locations around the airfoil's perimeter and then automatically marching the grid outward from the airfoil using the Hyperbolic Solver.

Gridgen's hyperbolic technique automatically handles the grid's periodicity so that the resulting mesh consists of a single zone. You can control the wall spacing and it's growth rate into the farfield and then watch the grid as it grows outward according to your specified number of steps.

Once the grid is completed, all of Gridgen's tools are then at your disposal for further grid modification and examination. In the examples shown below, Gridgen's Examine command was used to calculate and view several diagnotic measures such as quad cell skewness, aspect ratio, area, and size variation.

The hyperbolic solver may also be applied to grids more complicated than these airfoils - it can create volume grids by marching outward from an initial surface.
