CCMC regularly runs two versions of the SWMF for real-time geospace output. The original configuration,
designated here as SWMF2007, only includes the BATS-R-US MHD model and an ionospheric electrodynamics solver.
The newer configuration, designated here as SWMF2011, adds to the model suite the RCM inner magnetospheric
drift physics code. It also uses a more resolved grid in BATS-R-US.
