Abstract
A multigrid method for the membrane problem is studied. It turns out that some extra devices are needed in problems of elasticity if locking is present on the auxiliary grids. Symmetric successive relaxation is recommended for the smoothing steps whenever the matrices can be kept in the fast storage. Otherwise one may choose Jacobi relaxation. Finally some comments on preconditioned conjugate gradient methods are given.
