Parallel-in-Time with Fully Finite Element Multigrid for 2-D Space-fractional Diffusion Equations
Xiaoqiang Yue, Shi Shu, Xiaowen Xu +2
The paper investigates a non-intrusive parallel time integration with multigrid for space-fractional diffusion equations in two spatial dimensions. We firstly obtain a fully discre…

A Decoupling Two-grid Method for the Time-dependent Poisson-Nernst-Planck Equations
Ruigang Shen, Shi Shu, Ying Yang +1
We study a two-grid strategy for decoupling the time-dependent Poisson-Nernst-Planck equations describing the mass concentration of ions and the electrostatic potential. The comput…

Adaptive BDDC algorithms for the system arising from plane wave discretization of Helmholtz equations
Jie Peng, Junxian Wang, Shi Shu
Balancing domain decomposition by constraints (BDDC) algorithms with adaptive primal constraints are developed in a concise variational framework for the weighted plane wave least-…
