Discontinuous Galerkin methods for dispersive and lossy Maxwell's equations and PML boundary conditions
Tiao Lu,Pingwen Zhang,Wei Cai +2 more
TL;DR: In this paper, a unified formulation of discontinuous Galerkin method (DGM) for Maxwell's equations in linear dispersive and lossy materials of Debye type and in the artificial perfectly matched layer (PML) regions is presented.
Journal ArticleDOI
Moving mesh methods in multiple dimensions based on harmonic maps
Ruo Li,Tao Tang,Pingwen Zhang +2 more
TL;DR: This work will extend Dvinsky's method to provide an efficient solver for the mesh-redistribution algorithm, which adapts the mesh extremely well to the solution without producing skew elements for multi-dimensional computations.
Journal ArticleDOI
Nucleation of ordered phases in block copolymers.
TL;DR: Structural evolution of embryonic gyroid nucleus is predicted to follow two possible MEPs, revealing an interesting transition pathway with an intermediate perforated layered structure.
Journal ArticleDOI
A Moving Mesh Finite Element Algorithm for Singular Problems in Two and Three Space Dimensions
Ruo Li,Tao Tang,Pingwen Zhang +2 more
TL;DR: This work will further extend the moving mesh methods based on harmonic maps to deal with mesh adaptation in three space dimensions and solve an optimization problem with some appropriate constraints, which is in contrast to the traditional method of solving the Euler?Lagrange equation directly.
