Nernst effect in HYDRA

Summary form only given. The ICF design code HYDRA has been used to model Magnetized liner inertial fusion (MagLIF) experiments1 and NIF2 and Omega3 hohlraums with imposed magnetic fields. The current MHD package in HYDRA includes a resistive MHD solver, the dielectric pressure source term, anisotropic electron thermal conduction and magnetic field effects on alpha charged particle transport. We describe the addition of terms in the MHD package and their effect on representative simulations of interest to experimentalists. The most notable additional term is the Nernst term. This term affects both the magnetic field and electron temperature in the simulations. Of interest in the experiments is the effect on the region near the gold hohlraum wall and in the fuel region of the MagLIF concept. The terms are implemented using a discrete differential forms method which preserves the divergence free magnetic field exactly and provides a framework for proper variable centering.
