Figure 8From: Unconditionally energy stable second-order numerical scheme for the Allen–Cahn equation with a high-order polynomial free energyEvolution of \(\phi (x,y,t)\) with \(\epsilon =0.02\), \(\Delta x=\Delta y=\frac{1}{128}\), and \(\Delta t=10^{-5}\). In each case, times are \(t=0\), \(400\Delta t\), \(2000\Delta t\), and \(4000\Delta t\) (from left to right)Back to article page
