10.1.2 Examples of anisotropic adaptation

The Figure 3 shows an example of mesh adaptation where the metric is analytically defined (for more details, see [2]) An example of anisotropic adaptation on CFD simulation is represented on the Figure 4. Figure 5 shows an example of analytical surface captured with anisotropic mesh adaptation (see [3]).
