摘要
In this paper,we consider the application of the local discontinuous Galerkin method for the Allen-Cahn/Cahn-Hilliard system.The method in this paper extends the local discontinuous Galerkin method in[10]to the more general application system which is coupled with the Allen-Cahn and Cahn-Hilliard equations.Similar energy stability result as that in[10]is presented.Numerical results for the nonlinear problems which include the Allen-Cahn/Cahn-Hilliard system for one-dimensional and two-dimensional cases demonstrate the accuracy and capability of the numerical method.
