Energy dissipation law and maximum bound principle-preserving linear BDF2 schemes with variable steps for the Allen-Cahn equation
Bingyin Zhang, Hongfei Fu, Rihui Lan +1
In this paper, we propose and analyze a linear, structure-preserving scalar auxiliary variable (SAV) method for solving the Allen--Cahn equation based on the second-order backward…

Fractional-step High-order and Bound-preserving Method for Convection Diffusion Equations
Baolin Kuang, Hongfei Fu, Shusen Xie
In this paper, we derive two bound-preserving and mass-conserving schemes based on the fractional-step method and high-order compact (HOC) finite difference method for nonlinear co…

Strang splitting structure-preserving high-order compact difference schemes for nonlinear convection diffusion equations
Baolin Kuang, Shusen Xie, Hongfei Fu
In this paper, we present a class of high-order and efficient compact difference schemes for nonlinear convection diffusion equations, which can preserve both bounds and mass. For…
