An Optimal Block Diagonal Preconditioner for Heterogeneous Saddle Point Problems in Phase Separation

Abstract

The phase separation processes are typically modeled by Cahn-Hilliard equations. This equation was originally introduced to model phase separation in binary alloys; where phase stands for concentration of different components in alloy. When the binary alloy under preparation is subjected to a rapid reduction in temperature below a critical temperature, it… (More)
