We propose a robust 2D meshing algorithm, TriWild, to generate curved triangles
reproducing smooth feature curves, leading to coarse meshes designed to match the …

In this paper we discuss spectral properties of operators associated with the least-squares
finite-element approximation of elliptic partial differential equations. The convergence of the …

With this paper, our investigation of the finite element approximation on curved boundaries
using Raviart--Thomas spaces in the context of first-order system least squares methods is …

The finite element approximation on curved boundaries using parametric Raviart--Thomas
spaces is studied in the context of the mixed formulation of Poisson's equation as a saddle …

This article concerns the weak Galerkin mixed finite element method (WG-MFEM) for second
order elliptic equations on 2D domains with curved boundary. The Neumann boundary …

Abstract Recently, H⁢(div)-conforming finite element families were proven to be successful
on anisotropic meshes, with the help of suitable interpolation error estimates. In order to …

We present and analyze a least squares formulation for contact problems in linear elasticity
which employs both, displacements and stresses, as independent variables. As a …

The performance of least-squares finite element formulations for geometrically linear and
nonlinear problems is investigated in this work. We consider different elastic material …
