Convergence of the PML method for scattering problems in poroelastic media
Qianyuan Yin, Changkun Wei, Bo Zhang
This paper is concerned with the time-harmonic wave scattering problems in three dimensional poroelastic media. By introducing an intermediate variable , the original $\mathbf{u…
Local Relaxation Fast Poisson Methods on Hierarchical Meshes
Zhenli Xu, Qian Yin, Hongyu Zhou
The local relaxation algorithm is promising for fast solution of Poisson's equations, which computes the electric field distribution in a stepwise manner via local curl-free update…
Convergence of the PML method for thermoelastic wave scattering problems
Qianyuan Yin, Changkun Wei, Bo Zhang
This paper is concerned with the thermoelastic obstacle scattering problem in three dimensions. A uniaxial perfectly matched layer (PML) method is firstly introduced to truncate th…
Intrinsic local Gauss's law preserving PIC method: A self-consistent field-particle update scheme for plasma simulations
Zhonghua Qiao, Zhenli Xu, Qian Yin +1
In order to perform physically faithful particle-in-cell (PIC) simulations, the Gauss's law stands as a critical requirement, since its violation often leads to catastrophic errors…
