Phase-field modelling of crack in fixed grid

In phase field method how one can specify the crack in fixed grid?

In case of finite element method one uses two overlapping nodes to model crack, which nodes separate after crack propagation. In case of phase-field, generally people use fixed grid finite difference method. My question is how the same node point can show two different displacements when crack has passed through it like FEM?
