The applications of MHD (magnetohydrodynamics) devices have been rapidly developed in recent years. Thermo-electrically conducting fluid has been increasingly used in the manufacturing process of semiconducting material such as silicon crystal. In the present paper, we propose a new GSMAC (generalized simplified marker and cell) finite element method coupling with the B method. The present scheme efficiently satisfies both conservation laws of mass and magnetic flux. In order to verify the present scheme, we discuss the natural convection of thermo-electrically conducting fluids in a square cavity under a constant magnetic field. The numerical results obtained here agreed well with the past experimental and numerical results. Moreover, we estimate the effect of the induced heating term on a temperature field.
