摘要: 本文介绍了外维持场随时间变化条件下等离子体平衡方程(非线性椭圆型偏微分方程)的数值求解方法。文中着重叙述了差分方程组为直接解法,并与通常采用的松弛迭代法进行了比较,结果表明直接法比松弛法精度高且节省机时。

Abstract: Numerical method for solving the free boundary plasma equilibrium equation (a nonlinear partial differential equation of elliptic type) during the evolution of the external maintaining, field is presented. The direct method is employed to solve the corresponding set of difference equation and compared with the over relaxation method.It is shown that the direct method can give better computation precision and can save considerable computer time.
