We present a newly developed global magnetohydrodynamic(MHD) model to study the responses of the Earth’s magnetosphere to the solar wind. The model is established by using the space-time conservation element and solution element(CESE) method in general curvilinear coordinates on a six-component grid system. As a preliminary study, this paper is to present the model’s numerical results of the quasi-steady state and the dynamics of the Earth’s magnetosphere under steady solar wind flow with due northward interplanetary magnetic field(IMF). The model results are found to be in good agreement with those published by other numerical magnetospheric models.
