A divergence-free reconstruction of the nonconforming virtual element method for the Stokes problem

In this paper, we propose and investigate a divergence-free reconstruction of the nonconforming virtual element for the Stokes problem. By constructing the computable Raviart–Thomas-like interpolation operator, we guarantee the independence between the velocity error estimation |u−uh|1,h and the continuous pressure p, as it happens for the divergence-free flow solver. Moreover, this modified scheme can also inherit the advantages of the...
