本文描述了自由边界轴对称托卡马克等离子体及其控制系统的数值模型。等离子体的模拟与混合方法使用二维速度和通量函数与表面平均MHD方程描述的绝热不变量的演变。求解外部电路和附近导体中涡流影响的方程。该方法通过应用于几个测试问题进行了验证，并用于模拟PBX实验中豆形等离子体的形成。
We describe a numerical model of a free boundary axisymmetric tokamak plasma and its associated control systems. The plasma is modeled with a hybrid method using two-dimensional velocity and flux functions with surface-averaged MHD equations describing the evolution of the adiabatic invariants. Equations are solved for the external circuits and for the effects of eddy currents in nearby conductors. The method is verified by application to several test problems and used to simulate the formation of a bean-shaped plasma in the PBX experiment.
