MHD Simulations

The GORGON code is a 3D (x,y,z) or (r,z,theta) Eulerian resistive MHD code wich includes:

• Finite volume hydrodynamics - (Van Leer advection + constrained transport of magnetic field).

• Radiation loss model – optically thin, with optical depth limiter, or Radiation Transport - ( single group diffusion, 3 temperature – electron, ion, radiation).

• EOS – (either average atom, multi-material, or Saha, or corrected Thomas-Fermi models).

• Resistive diffusion – ( either implicit B-field or explicit A-field representation) .

• Synthetic diagnostics output ( gated X-ray images, radiography, laser probing etc.).

• Fully explicit version allows efficient parallel implementation.

• Used for wire array Z-pinch, X-pinch, laboratory astrophysics and long-pulse LPI.
