In this talk, I will also introduce the SAV and Lagrange multiplier approach which preserve energy dissipative and physical constraints for gradient systems in discrete level. The advantage of these methods only require solving linear equation with constant coefficients at each time step plus an additional nonlinear algebraic system which can be solved at negligible cost. Ample numerical results for phase field models are presented to validate the effectiveness and accuracy of the proposed numerical schemes.
