The goals and highlights of this research are to: 1) Undertake two-fluid simulations of oblique tearing modes with $$m_{i}/m_{e}$$ = 100 and 1836, and $$b_g$$ ≤ 10 with further bridging the fluid and kinetic models and linear growth rates agree with kinetic theory for $$b_g$$ ≤ 1; 2) 3-D simulations of a doubly-periodic Harris Sheet with $$m_{i}/m_{e}$$ = 100 and $$b_g$$ = 2:5 that features current layer splits into multiple ~ de-scale diffusion regions, an amplification of current by 2x, and similar features to kinetic simulations; 3) Influence of boundary conditions: periodic vs. line-tied; and 4) Address how much of the kinetic nature of MR can be captured by a two-fluid model. (A fluid model requires dissipation.)
