Abstract
The characteristics of near-unity- Β equilibria are investigated with two codes. CUBE is a multigrid Grad-Shafranov solver [Gourdain, J. Comput. Phys. 216, 275 (2006)], and Ophidian was written to compute solutions using analytic unity- Β equilibria [Cowley, Phys. Fluids B 3, 2066 (1991)]. Results from each method are qualitatively and quantitatively compared across a spectrum of mutually relevant parameters. These comparisons corroborate the theoretical results and provide benchmarks for high-resolution numerical results available from CUBE. Both tools facilitate the exploration of the properties of high- Β equilibria, such as a highly diamagnetic plasma and its ramifications for stability and transport.
