摘要:Exponential time differencing (ETD) methods will be developed for solving phase field equations. ETD method is a very efficient ordinary differential equation solver, which solves the linear part of the equation exactly by using the exponential integral factors and keep exponential behavior of the system. Our numerical schemes preserve the property of energy decay in the discrete sense, which is the fundamental physical feature of the solutions to phase field models as the gradient flows.
