Numerical simulation of tearing mode suppression by applying non-resonant magnetic perturbations (non-RMPs) has been carried out in the J-TEXT tokamak based on the NIMROD (Non-Ideal Magnetohydrodynamics with Rotation, Open Discussion) code. In the present work, we investigate the growth of n = 1 and n = 2 (n is the toroidal mode number) magnetohydrodynamics (MHD) instabilities, mainly as tearing modes, in response to different modes and amplitudes of non-RMPs generated by the external helical coils. It is found that the tearing mode can be stabilized by non-RMPs, especially for the non-RMPs with mode m/n = -1/1 (m is the poloidal mode number) and coil current IMP = 4kA.
