摘要
A mixed finite element method requiring only continuous finite elements is presented for the approximation of the solution of the fourth order Cahn-Hilliard equation of phase separation and for the Sivashinsky equation of solid-liquid interface in binary alloys. Optimal error bounds are derived in various norms, and numerical results for the one-dimensional Cahn-Hilliard equation are given using Crank-Nicolson time discretization.
