Y. Achdou et al., ITERATIVE SUBSTRUCTURING METHODS FOR THE MORTAR ELEMENTS, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 322(2), 1996, pp. 185-190
For elliptic problems, the mortar method lets us to couple different d
iscretizations in different subdomains. For problems in the plane, we
propose an iterative substructuring algorithm for the efficient soluti
on of the linear systems arising from this methods.
