Analysis of a Multigrid Algorithm for Mortar Element Method

  •  Jianxin Dai    


In this paper, a multigrid algorithm is studied for mortar element method for rotated Q1 element, the mortar
condition is only dependent on the degrees of the freedom on subdomains interfaces. We prove the convergence
of W-cycle multigrid and construct a variable V-cycle multigrid preconditioner which is available.
