A $C^1$ Virtual Element Method for the Cahn--Hilliard Equation with Polygonal Meshes
A $C^1$ Virtual Element Method for the Cahn--Hilliard Equation with Polygonal Meshes
In this paper we develop an evolution of the $C^1$ virtual elements of minimal degree for the approximation of the Cahn--Hilliard equation. The proposed method has the advantage of being conforming in $H^2$ and making use of a very simple set of degrees of freedom, namely, 3 degrees of freedom …
