"WebThe time discretization method can usually be divided into two categories: one is the method of explicit methods such as Runge-Kutta method, linear multi-step method and so on. The method does not need to form the total stiffness matrix. However, since the Allen-Cahn equation group (1) is rigid, it has a strict constraint on the explicit time step.
