General Description
This is a pseudo solver (i.e. it is not solving an equation).
This solver is used for the mesh adaptation (Mesh Adaptation) to perform the intersection of two anisotropic metric M_1 and M_2.
The intersection of two metrics M_1 and M_2 is given by (Alauzet et al., 2007):
with the matrix where the columns are the normalised eigenvectors
, of
and
.
M_1 and M_2 can be computed using the MMG2D_MetricAniso Solver.
A variable containing the metric M_i must have 3 dofs (M_{11},M_{22},M_{12}).
