Abstract: The paper dercribes a numerical method for the resistivity gradient driven turbulence in the Tokamak edge. The mode selection for the mode-mode coupling or nonlinear interaction is discussed. The corresponding computer code for three-dimension magnetic hydrodynamics equations has been constructed, which can save the computation time effectively.

Key words: difference method, turbulent nonlinearity, DIA
