Description

A three-dimensional global magnetohydrodynamics simulation code developed by the University of Michigan and made publicly runnable through NASA's Community Coordinated Modeling Center.

Components

• BATS-R-US global MHD simulations run through NASA's Community Coordinated Modeling Center as a public undergraduate lab resource: BATS-R-US (Block-Adaptive-Tree-Solarwind-Roe-Upwind-Scheme) solves the 3D magnetohydrodynamics equations in finite volume form using Roe's Approximate Riemann Solver on an adaptive grid. Students run it on NASA supercomputers at the CCMC, where simulation runs can be requested by the public and results explored and visualized through a standard web browser. The authors note the CCMC resources allow access to powerful simulations without local supercomputer hardware or installing and maintaining simulation codes, and that thorough documentation makes explaining run requests relatively easy. (Crumley et al. (2007))

Claims

• Students achieve reasonable agreement between their magnetopause-crossing findings and model predictions, gaining exposure to the tools and techniques of space physics [+W]
• Students' empirical fits of simulated magnetopause locations show good internal agreement, though student estimates and simulation-calculated locations often disagree beyond uncertainties [+W]
• Using a stair-step pattern of solar wind input conditions in the simulation portion of the lab led to much better student results than linearly varying conditions [+W]
