Cahn–hilliard equation
Webto solve the Allen-Cahn and Cahn-Hilliard equations. Since an essential feature of the Allen-Cahn and Cahn-Hilliard equations are that they satisfy the energy laws (1.4) and (1.5) respectively, it is important to design efficient and accurate numer-ical schemes that satisfy a corresponding discrete energy law, or in other words, energy stable.
