FETI-DP for the Three Dimensional Virtual Element Method [PDF]
SIAM Journal on Numerical Analysis, 2020 We deal with the Finite Element Tearing and Interconnecting Dual Primal (FETI-DP) preconditioner for elliptic problems discretized by the virtual element method (VEM). We extend the result of [22] to the three dimensional case. We prove polylogarithmic condition number bounds, independent of the number of subdomains, the mesh size, and jumps in the ...

When rational functions meet virtual elements: the lightning virtual element method
CalcoloAbstractWe propose a lightning Virtual Element Method that eliminates the stabilisation term by actually computing the virtual component of the local VEM basis functions using a lightning approximation. In particular, the lightning VEM approximates the virtual part of the basis functions using rational functions with poles clustered exponentially close

SUPG-stabilized stabilization-free VEM: a numerical investigation
Mathematics in EngineeringWe numerically investigate the possibility of defining Stabilization-Free Virtual Element discretizations–i.e., Virtual Element Method discretizations without an additional non-polynomial non-operator-preserving stabilization term–of advection-diffusion ...

A Virtual Element Method for elastic and inelastic problems on polytope meshes [PDF]
, 2015 We present a Virtual Element Method (VEM) for possibly nonlinear elastic and inelastic problems, mainly focusing on a small deformation regime. The numerical scheme is based on a low-order approximation of the displacement field, as well as a suitable ...

Virtual Element Methods Without Extrinsic Stabilization
SIAM Journal on Numerical AnalysisVirtual element methods (VEMs) without extrinsic stabilization in arbitrary degree of polynomial are developed for second order elliptic problems, including a nonconforming VEM and a conforming VEM in arbitrary dimension. The key is to construct local $H(\textrm{div})$-conforming macro finite element spaces such that the associated $L^2$ projection of ...
