A Second-Order Maximum-Bound-Preserving and Energy-Stable Exponential Time-Differencing Method for Allen--Cahn-Type Gradient Flows
Wenshuai Hu, Guanghua Ji, Xiao Li
The energy dissipation law and the maximum bound principle (MBP) are two important physical features of the well-known Allen--Cahn equation. In this paper, we develop and analyze n…
Energy stability and error estimates for a second-order structure-preserving exponential integrator method for smectic-A liquid crystals
Wenshuai Hu, Guanghua Ji, Xiao Li
In this work, we develop a second-order, linear, decoupled, and structure-preserving numerical scheme for the modified Landau--de Gennes model of smectic-A (SmA) liquid crystals. T…
