Detailed Description

Multigrid solver on a level.

: Invoke relaxation step. Default is pure MG V-cycle, suitable for use in multilevel solver application; otherwise, use approximate solver such as CG at bottom level. It is assumed that the problem has already been put in residual-correction form. In particular, only the homogeneous form of the physical and coarse-fine boundary conditions need be invoked.
