Nonlinear magnetohydrodynamic(MHD) simulations of an equilibrium on the J-TEXT tokamak with applied resonant magnetic perturbations(RMPs) are performed with NIMROD(non-ideal MHD with rotation,open discussion).Numerical simulation of plasma response to RMPs has been developed to investigate magnetic topology,plasma density and rotation profile.The results indicate that the pure applied RMPs can stimulate 2/1 mode as well as 3/1 mode by the toroidal mode coupling,and finally change density profile by particle transport.At the same time,plasma rotation plays an important role during the entire evolution process.
