Documentation

(Optional) Defines the outer relaxation weight for hybrid SOR and SSOR on all levels.

omega > 0 this assigns the same outer relaxation weight omega on each level
omega = -k an outer relaxation weight is determined with at most k CG steps on each level
(this only makes sense for symmetric positive definite problems and smoothers, e.g. SSOR)

The default is 1.
