The nonconforming virtual element method with curved edges

Lourenco Beirão Da Veiga, Yi Liu, Lorenzo Mascotto +1

We introduce a nonconforming virtual element method for the Poisson equation on domains with curved boundary and internal interfaces. We prove arbitrary order optimal convergence i…

Stability and interpolation properties for Stokes-like virtual element spaces

L. Beirão da Veiga, L. Mascotto, J. Meng

We prove stability bounds for Stokes-like virtual element spaces in two and three dimensions. Such bounds are also instrumental in deriving optimal interpolation estimates. Further…

The Stokes complex for Virtual Elements in three dimensions

L. Beirao da Veiga, F. Dassi, G. Vacca

The present paper has two objectives. On one side, we develop and test numerically divergence free Virtual Elements in three dimensions, for variable ``polynomial'' order. These ar…

The Stokes complex for Virtual Elements with application to Navier--Stokes flows

L. Beirão da Veiga, D. Mora, G. Vacca

In the present paper, we investigate the underlying Stokes complex structure of the Virtual Element Method for Stokes and Navier--Stokes introduced in previous papers by the same a…

The Virtual Element Method with curved edges

L. Beirão da Veiga, A. Russo, G. Vacca

In this paper we initiate the investigation of Virtual Elements with curved faces. We consider the case of a fixed curved boundary in two dimensions, as it happens in the approxima…

Arbitrary order 2D virtual elements for polygonal meshes: Part II, inelastic problem

Edoardo Artioli, Lourenco Beirão da Veiga, Carlo Lovadina +1

The present paper is the second part of a twofold work, whose first part is reported in [3], concerning a newly developed Virtual Element Method (VEM) for 2D continuum problems. Th…

Arbitrary order 2D virtual elements for polygonal meshes: Part I, elastic problem

Edoardo Artioli, Lourenco Beirao da Veiga, Carlo Lovadina +1

The present work deals with the formulation of a Virtual Element Method (VEM) for two dimensional structural problems. The contribution is split in two parts: in part I, the elasti…

A virtual element method for the acoustic vibration problem

Lourenço Beirão da Veiga, David Mora, Gonzalo Rivera +1

We analyze in this paper a virtual element approximation for the acoustic vibration problem. We consider a variational formulation relying only on the fluid displacement and propos…

Serendipity Nodal VEM spaces

L. Beirao da Veiga, F. Brezzi, L. D. Marini +1

We introduce a new variant of Nodal Virtual Element spaces that mimics the "Serendipity Finite Element Methods" (whose most popular example is the 8-node quadrilateral) and allows…

Basic principles of hp Virtual Elements on quasiuniform meshes

L. Beirão da Veiga, A. Chernov, L. Mascotto +1

In the present paper we initiate the study of Virtual Elements. We focus on the case with uniform polynomial degree across the mesh and derive theoretical convergence estimate…

Numerical results for mimetic discretization of Reissner-Mindlin plate problems

Lourenco Beirao da Veiga, Carlo Lovadina, David Mora

A low-order mimetic finite difference (MFD) method for Reissner-Mindlin plate problems is considered. Together with the source problem, the free vibration and the buckling problems…

An isogeometric method for the Reissner-Mindlin plate bending problem

L. Beirão da Veiga, A. Buffa, C. Lovadina +2

We present a new isogeometric method for the discretization of the Reissner-Mindlin plate bending problem. The proposed scheme follows a recent theoretical framework that makes pos…
