摘要：We first introduce a conservative nonconforming virtual element method for the full stationary incompressible magnetohydrodynamics model. Then propose the grad-div conforming virtual element method for the quad-div problem in three dimensions by a de Rham sub-complex with enhanced smoothness. These methods keep some divergence-free property. The stability and optimal error estimates are given. Finally, some numerical experiments are presented to validate the theoretical analysis.
