Numerical modeling of anisotropic ferroelectric materials with hybridizable discontinuous Galerkin methods
Wenyu Lei
We investigate a gradient flow structure of the Ginzburg--Landau--Devonshire (GLD) model for anisotropic ferroelectric materials by reconstructing its energy form. We show that the…

Adaptive finite element approximations for elliptic problems using regularized forcing data
Luca Heltai, Wenyu Lei
We propose an adaptive finite element algorithm to approximate solutions of elliptic problems whose forcing data is locally defined and is approximated by regularization (or mollif…

Approximation of the spectral fractional powers of the Laplace-Beltrami Operator
Andrea Bonito, Wenyu Lei
We consider numerical approximations of spectral fractional Laplace-Beltrami problems on closed surfaces. The proposed numerical algorithms rely on their Balakrishnan integral repr…
