ALEGRA-MHD

  • All hydrodynamics/solid dynamic modules of "base" ALEGRA and with the addition of magnetic field and thermal transport effects.

    Flyer plate simulation

    Flyer plate simulations are used to design equation of state experiments on Z

  • Lorentz forces, Joule heating, thermal transport and simple models for radiating excess energy

  • 2D and 3D versions -- 2D modeling with the magnetic flux density vector components in or out of the plane with the corresponding current density out of or in the plane, respectively.

  • 3D uses a magnetic diffusion solution based on edge and face elements which maintains the discrete flux divergence-free property during magnetic solve and constrained transport remap stage

  • Lumped element coupled circuit equations

  • Magnetic and thermal conduction

  • Advanced models for thermal and electrical conductivity

  • Emission model radiates excess energy when medium is optically thin while accounting for reabsorption
