Grid Generation: Examples
Fig. 1 shows the effect of using an algebraic grid generator to a problem with severe
concavities. A Laplace smoothing applied to the transfinite grid has shown some

2-D Surface Control
As an example of surface control, Fig. 3 shows the effect of
correcting the point bunching on a 2-D airfoil by moving iteratively
points along a spline curve (spline point movement technique).

Once the surface grid is set a grid can be wasily generated with a hyperbolic method, as shown in Fig. 4 below.

Fig. 5 below shows a multi-block structured surface grid for a 2-element inverted wing (Indy car model, rear wing). The read lines denote the block structure.
