Comparison of two-dimensional and three-dimensional MHD equilibrium and stability codes [report]

1986 unpublished
Stability results obtained with the fully three-dimensional magnetohydrodynamio code BETA, the helically invariant code HERA, and the asymptotic stellarator expansion code STEP agree well For a straight t, = 2, M = 5 stellarator model. This good agreement between the BETA and STEP codes persists as toroidal curvature is introduced. This validation provides justification for confidence in work with these models.
