A new class of efficient and robust energy stable schemes for gradient flows

J Shen, J Xu, J Yang - SIAM Review, 2019 - SIAM
We propose a new numerical technique to deal with nonlinear terms in gradient flows. By
introducing a scalar auxiliary variable (SAV), we construct efficient and robust energy stable …

Improving the accuracy and consistency of the scalar auxiliary variable (SAV) method with relaxation
