Penalty Virtual Element Method for the 3D Incompressible Flow on Polyhedron Mesh [PDF]
Entropy, 2022 In this paper, a penalty virtual element method (VEM) on polyhedral mesh for solving the 3D incompressible flow is proposed and analyzed. The remarkable feature of VEM is that it does not require an explicit computation of the trial and test space ...

Stability Analysis for the Virtual Element Method [PDF]
Mathematical Models and Methods in Applied Sciences, 2016 We analyse the Virtual Element Methods (VEM) on a simple elliptic model problem, allowing for more general meshes than the one typically considered in the VEM literature.

The Virtual Element Method with curved edges [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2018 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 approximation of problems posed on a curved domain or with a curved interface ...

The nonconforming virtual element method for eigenvalue problems [PDF]
ESAIM: Mathematical Modelling and Numerical Analysis, 2018 We analyse the nonconforming Virtual Element Method (VEM) for the approximation of elliptic eigenvalue problems. The nonconforming VEM allow to treat in the same formulation the two- and three-dimensional case.We present two possible formulations of the ...

An Immersed Virtual Element Method Based on Interface Problems
Journal of Harbin University of Science and Technology, 2023 An immersed virtual element method is developed to solve the second-order interface problems in two-dimensional space , which overcomes the problem that the constructed space cannot satisfy both the coordination and jump conditions. The key idea is to

Acta Numerica, 2023 The present review paper has several objectives. Its primary aim is to give an idea of the general features of virtual element methods (VEMs), which were introduced about a decade ago in the field of numerical methods for partial differential equations, in order to allow decompositions of the computational domain into polygons or polyhedra of a very ...
