A two-level enriched finite element method for a mixed problem [PDF]
, 2011 The simplest pair of spaces is made inf-sup stable for the mixed form of the Darcy equation. The key ingredient is to enhance the finite element spaces inside a Petrov-Galerkin framework with functions satisfying element-wise local Darcy problems with ...

Virtual Element Approximation of Eigenvalue Problems
, 2020 We discuss the approximation of eigenvalue problems associated with elliptic partial differential equations using the virtual element method. After recalling the abstract theory, we present a model problem, describing in detail the features of the scheme,

A Coupled Overlapping Finite Element Method for Analyzing Underwater Acoustic Scattering Problems
Journal of Marine Science and Engineering, 2023 It is found that the classic finite element method (FEM) requires much time for adequate meshes to acquire satisfactory numerical solutions, and is restricted to acoustic problems with low and middle frequencies.

On mesh coarsening procedures for the virtual element method
CoRR, 2023 In the context of adaptive remeshing, the virtual element method provides significant advantages over the finite element method. The attractive features of the virtual element method, such as the permission of arbitrary element geometries, and the seamless permission of 'hanging' nodes, have inspired many works concerning error estimation and ...

Isoparametric Virtual Element Methods
CoRRWe present two approaches to constructing isoparametric Virtual Element Methods of arbitrary order for linear elliptic partial differential equations on general two-dimensional domains. The first method approximates the variational problem transformed onto a computational reference domain.

Two-grid virtual element discretization of quasilinear elliptic problem
Mathematical Modelling and AnalysisIn this paper a two grid algorithm for quasilinear elliptic problem based on virtual element method (VEM) discretization is proposed. With this new algorithm the solution of a quasilinear elliptic problem on a fine grid is reduced to the solution of a ...
