PoissonSolverMGRelaxationFactor
PoissonSolverMGRelaxationFactor
Section Hamiltonian::Poisson::Multigrid
Type float
Relaxation factor of the relaxation operator used for the
multigrid method. This is mainly for debugging,
since overrelaxation does not help in a multigrid scheme.
The default is 1.0, except 0.6666 for the gauss_jacobi method.
