Dietrich Braess, Peter Deuflhard and Konstantin Lipnikov, "A subspace cascadic multigrid method for mortar elements", Computing, vol. 69, no. 3, pp. 205-225, 2002


A cascadic multigrid (CMG) method for elliptic problems with strong material jumps is proposed and analyzed. Non--matching grids at interfaces between subdomains are allowed and treated by mortar elements. The arising saddle point problems are solved by a subspace confined conjugate gradient method as smoother for the CMG. Details of algorithmic realization including adaptivity are elaborated. Numerical results illustrate the efficiency of this CMG algorithm.
