High-speed numerical code 'AEOLUS-R1' for resistive MHD instability with single helicity

  • 1. Japan Atomic Energy Research Inst., Tokai, Ibaraki. Tokai Research Establishment

Description

The nonlinear resistive MHD code AEOLUS-RI developed solves a set of 2-dimensional equations with helical symmetry, which is derived from full MHD equations. Finite difference method for radial direction and Fourier expansion with respect to angular variable are employed. Combination of Crank-Nicolson implicit method and leapfrog method are used for the time integration. This numerical scheme reduces CPU time to 1/10 -- 1/15 that by simple explicit method. Using this code, sawtooth oscillation due to m = 1/n = 1 mode and island formation due to m = 2/n = 1 mode are recovered. (author)
