Efficient numerical solution of the Allen–Cahn equation via a non-lumping Galerkin finite element method

AIP Advances
This work elaborates and investigates an effective numerical method for solving nonlinear Allen–Cahn equation. In particular, we focused on a time discretization scheme using the Crank–Nicolson (CN) method combined with space discretization using the non-
