-snes_ms_type | - type of multi-stage smoother | |
-snes_ms_damping | - damping for multi-stage method |
Multi-stage smoothers should usually be preconditioned by point-block Jacobi to ensure proper scaling and to normalize the wave speeds.
The methods are specified in low storage form (Ketcheson 2010). New methods can be registered with SNESMSRegister().
