Here, we use an error estimate based on the interpolation error, proposed by Frey and Alauzet (2005). Routines to compute the anisotropic metric defining the mesh size have been implemented as Elmer/Ice Solvers. The mesh adaptation is performed using the freely available library MMG ([[http:// | Here, we use an error estimate based on the interpolation error, proposed by Frey and Alauzet (2005).
