-robust error estimates of general non-uniform time-step numerical schemes for reaction-subdiffusion problems
Jiwei Zhang, Zhimin Zhang, Chengchao Zhao
Numerous error estimates have been carried out on various numerical schemes for subdiffusion equations. Unfortunately most error bounds suffer from a factor or ,…
Fully Conservative Difference Schemes for the Rotation-Two-Component Camassa-Holm System with Smooth/Nonsmooth Initial Data
Tong Yan, Jiwei Zhang, Qifeng Zhang
The rotation-two-component Camassa--Holm system, which possesses strongly nonlinear coupled terms and high-order differential terms, tends to have continuous nonsmooth solitary wav…
Second order convergence of a modified MAC scheme for Stokes interface problems
Haixia Dong, Zhongshu Zhao, Shuwang Li +2
Stokes flow equations have been implemented successfully in practice for simulating problems with moving interfaces. Though computational methods produce accurate solutions and num…
High performance implementation of 3D FEM for nonlocal Poisson problem with different ball approximation strategies
Gengjian Chen, Yuheng Ma, Jiwei Zhang
Nonlocality brings many challenges to the implementation of finite element methods (FEM) for nonlocal problems, such as large number of queries and invoke operations on the meshes.…
