Our main tools for MHD simulations are NIMROD, HiFi and to a lesser extent BOUT++. We have served several contracts with the NIMROD code, and we are exploring the use of HiFi for 3D geometries, particularly for the W7X stellarator. BOUT++ is running, and cross-code verification activities are planned. We added OpenFOAM recently to the list of MHD code we run, primarily because of interest in incompressible MHD for fluid flows in blankets. BOUT++ is written with C++, whereas NIMROD and HiFi are written in FORTRAN.

NIMROD

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.

3D resistive MHD code NIMROD provides insight into the ARPA-E supported plasma compression experiment at Swarthmore college. Shown are contour plots of B_toroidal and density at 5 time points for a compact torus that is peristaltically accelerated by a compression coil.

HiFi

The distinguishing capabilities of the HiFi code include adaptive spectral element spatial representation with flexible 3D geometry, highly parallelizable implicit time advance, and general flux-source form of the partial differential equations and boundary conditions that can be implemented in its framework. Early algorithm development and extensive verification studies of the two-dimensional version of the code have been previously described [A.H. Glasser & X.Z. Tang, Comp. Phys. Comm., 164 (2004); V.S. Lukin, Ph.D. thesis, Princeton University (2008)].

BOUT++

BOUT++ is a 3D plasma fluid simulation code which has been developed at York in collaboration with the MFE group at LLNL and the MCS division at ANL. Key features are:

OpenFOAM

The OpenFOAMĀ® (Open Field Operation and Manipulation) CFD Toolbox is a free, open source CFD software package which has a large user base across most areas of engineering and science, from both commercial and academic organisations. The package includes an MHD solver: mhdFoam

The mhdFoam solver is currently an incompressible magnetohydrodynamic equation solver. It solves the coupled Maxwell-Navier-Stokes equations for an incompressible fluid. The fluid electrical conductivity is presumed constant.
