NIMROD Magnetohydrodynamic Code Team Homepage

NIMROD solves the fully 3D, extended-magnetohydrodynamic equations using:

• Spectral finite element discretization in two dimensions,
• Finite Fourier series in the third dimension,
• Semi-implicit and implicit temporal discretization for the range of temporal scales found in fusion experiments,
• Bulk kinetic effects using continuum drift-kinetic closures,
• Particle and continuum methods for the effect of a minority species of energetic particles or run-away electrons,
• Time-split integration of atomic-rate effects such as ionization and radiation.

NIMROD has simulated aspects of a wide range of fusion experiments (tokamaks, stellarators, spheromaks, reversed-field pinches, z-pinches, field-reversed configurations, etc.), laboratory plasma-physics experiments and astrophysical plasmas. Examples of NIMROD usage can be found in our NIMROD publications, team meetings and presentations pages.
