Detailed Description

Hydrofracture strategy.

dofLabel: 0 = displacement, x-component dofLabel: 1 = displacement, y-component dofLabel: 2 = displacement, z-component dofLabel: 3 = pressure

Ingredients:

1. F-points displacement (0,1,2), C-points pressure (3)
2. F-points smoother: AMG, single V-cycle, separate displacement components
3. C-points coarse-grid/Schur complement solver: boomer AMG
4. Global smoother: none
