摘要: 对于激光物理研究中提出的一个非线性热传导问题,利用Saul'yev非对称格式构造了适合并行计算的分组隐式解法.数值试验表明,新算法与通常的隐式算法计算精度相当,迭代次数相同.

关键词: 非线性, 热传导方程, 并行算法

Abstract: By using Saul'yev asymmetric schemes, the group implicit method is developed for the nonlinear heat equation appearing in laser physics, which has the obvious property of parallelism. Numerical experiments show that the new method has the similar accuracy with the known implicit method, and the numbers of iteration in both cases are nearly the same.

Key words: nonlinear, heat equation, parallel algorithm
