Anisotropic triangle and quad meshing with
CM2 TriaMesh Aniso^® and CM2 QuadMesh Aniso^®

In all these examples, a background mesh has been used to specify the metric field over the domain.
For the "gaussian hat" example, the background mesh is generated automatically in the 3-D surface meshing routine. For the other examples, a user-defined background mesh has been used.

See also the examples of remeshing on 3-D tessellated (STL) surfaces.
