We present the construction of the new element in two and three dimensions, highlighting the main differences with the conforming VEM and the classical nonconforming finite element methods. We provide the error analysis and establish the equivalence with a family of mimetic finite difference methods. Numerical experiments verify the theory and validate the performance of the proposed method.en0764-583X20163879904Elliptic problemsNonconforming methodPoisson equationUnstructured meshesVirtual element methodJournal Article10.1051/m2an/2015090Other
