About NIMROD

NIMROD solves the 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,
• Simulation particles for kinetic effects from a minority species of energetic ions,
and
• Integro-differential methods for kinetic effects from free-streaming.
