We present a fast evolution numerical algorithm for solving the Allen–Cahn (AC) equations. One of efficient computational techniques for the AC equation is the operator splitting method. We split the AC equation into the linear heat and nonlinear e

In this paper, we present a simple and accurate adaptive time-stepping algorithm for the Allen–Cahn (AC) equation. The AC equation is a nonlinear partial differential equation, which was first proposed by Allen and Cahn for antiphase boundary motio

In this study, we present benchmark problems for the numerical methods of the phase-field equations. To find appropriate benchmark problems, we first perform a linear stability analysis and then take a growth mode solution as the benchmark problem, w
