A Convex Splitting Spectral Method for the Phase Field Crystal Equation: Energy Stability, Computational Stability Maps, and Three-Dimensional GPU Simulations

Saulo Orizaga, Peimeng Yin, Deep Choudhuri

The paper introduces a Fourier spectral method based on convex splitting for the phase field crystal equation that is unconditionally energy stable, conserves mass, and can be effi…
