On the choice of the internal degrees of freedom for the nodal Virtual Element Method in two dimensions

摘要

The Virtual Element Method (in short VEM) is a recent generalization of the Finite Element Method that can easily handle general polygonal and polyhedral meshes. In this short note we will present three variants of the Virtual Element Method, the only difference being the number of internal degrees of freedom. We will see that all methods behave in a very similar way. (C) 2016 Elsevier Ltd. All rights reserved.
