The discontinuous Galerkin methods are locally conservative, high‐order accurate, and
robust methods that can easily handle elements of arbitrary shapes, irregular triangulations …

We present a new hybridizable discontinuous Galerkin (HDG) method for the convection
diffusion problem on general polyhedral meshes. This new HDG method is a generalization …

The power conversion efficiency of an ultrathin CuIn_1− ξGa_ξSe_2 (CIGS) solar cell was
maximized using a coupled optoelectronic model to determine the optimal bandgap grading …

This paper proposes and analyzes a weak Galerkin (WG) finite element method for 2-and 3-
dimensional convection–diffusion–reaction problems on conforming or nonconforming …

In this article, we present a theoretical framework for integrating discontinuous Galerkin
methods in the variational multiscale paradigm. Our starting point is a projector-based …

We study the numerical approximation of singularly perturbed convection-diffusion problems
on one-dimensional pipe networks. In the vanishing diffusion limit, the number and type of …

A coupled optoelectronic model was implemented along with the differential evolution
algorithm to assess the efficacy of grading the bandgap of the Cu 2 ZnSn (S ξ Se 1–ξ) 4 …

We analyze a space-time hybridizable discontinuous Galerkin method to solve the time-
dependent advection-diffusion equation on deforming domains. We prove stability of the …

We propose a robust a posteriori error estimator for the hybridizable discontinuous Galerkin
method for convection–diffusion equations with dominant convection. The reliability and …

A design tool was formulated for optimizing the efficiency of inorganic, thin-film, photovoltaic
solar cells. The solar cell can have multiple semiconductor layers in addition to antireflection …
