摘要：Recently, many time-dependent problems are newly brought forward as large Tokamaks and helical systems are operated. In order to explain physical mechanisms of MHD phenomena including above ones, we are developing a 3D incompressible MHD code in the generalized coordinate system. The equations of time-dependent incompressible MHD code in the conservative nondimensional from are as follows; [numerical formula] where B is the magnetic field, v is the velocity, p is the pressure, and s is the Lundquist number. The time development of the above equations is solved by the second-order Adams-Bashforth scheme and the fourth-order central differencing method for the space derivatives is used.
