 note = {Behaviors of low poloidal (m) and toroidal (n) Fourier modes in the Large Helical Device (LHD) are investigated by means of direct numerical simulations (DNS) of fully three-dimensional, nonlinear and compressible
magnetohydrodynamics (MHD) equations. Starting from an ideal equilibrium with the position of vacuum magnetic
axis Rax = 3.6 m and β0 = 4% finite pressure, a m/n = 2/1 mode grows in the DNS. Fluid motions on poloidal sections
are governed by the two pairs of anti-parallel vortex pairs associated with the m/n = 2/1 modes. The vortex pairs
transport plasma pressure from the core to edge region and bring about large pressure deformations. It is also shown that the toroidal part in the kinetic energy and the enstrophy are comparable to the poloidal parts of them. The numerical results demonstrate importance of investigating three-dimensional behaviors of MHD plasmas in LHD.},
