摘要: 对托卡马克等离子体内部输运垒触发机制的动力学特征进行了数值模拟,通过区域分解法实现了数值模拟程序并行化,并行效率随计算机规模的增加而提高,结果与理论分析相吻合.并行模拟程序也适合MHD非线性撕裂模的数值求解.

关键词: 触发机制, 数值模拟, 并行计算

Abstract: Numerical simulation of dynamic behaviour of internal transport with a barrier trigger in Tokamak plasmas in splitting domain and its parallel computation are shown.The parallel efficiency increases with the computing scale.Numerical results agree well with theoretical analysis.The code adapts to the simulation of nonlinear tearing mode (specially mutiple mode) as well.

Key words: triggering mechanism, numerical simulations, parallel computing
