We present a four-field virtual element discretization for the time-dependent resistive magnetohydrodynamics equations in three space dimensions, focusing on the semi-discrete formulation. The proposed method employs general polyhedral meshes and guarantees velocity and magnetic fields that are divergence free up to machine precision.We provide a full convergence analysis under suitable regularity assumptions, which is validated by some numerical tests.

Abstract
We present a four-field virtual element discretization for the time-dependent resistive magnetohydrodynamics equations in three space dimensions, focusing on the semi-discrete formulation. The proposed method employs general polyhedral meshes and guarantees velocity and magnetic fields that are divergence free up to machine precision.We provide a full convergence analysis under suitable regularity assumptions, which is validated by some numerical tests.File in questo prodotto:
