本文给出固定边界发汗控制方程显式与隐式差分解法的并行化方法.数值试验表明隐式差分格式的数值稳定性的条件比显式差分格式的条件要宽松得多,这与理论分析的结果是一致的;数值试验还表明显式方法的加速比及效率均高于隐式方法,但隐式方法的时间步长可以放大,从整体上更节省CPU时间.本文给出固定边界发汗控制方程显式与隐式差分解法的并行化方法.数值试验表明隐式差分格式的数值稳定性的条件比显式差分格式的条件要宽松得多,这与理论分析的结果是一致的;数值试验还表明显式方法的加速比及效率均高于隐式方法,但隐式方法的时间步长可以放大,从整体上更节省CPU时间.
In this paper, we give a parallel method of explicit and implicit difference solution to the governing equation of constant boundary swell.The numerical experiments show that the numerical stability of implicit difference scheme is much more relaxed than the explicit difference scheme, which is in agreement with the theoretical analysis The numerical results also show that the explicit method has higher speedup and efficiency than the implicit method, but the implicit method can amplify the time step and save the CPU time as a whole.In this paper, the fixed boundary sweat control Equation parallel method with implicit difference method.The numerical experiments show that the numerical stability of implicit difference scheme is much more relaxed than that of explicit difference scheme, which is consistent with the theoretical analysis. Numerical experiments It also shows that the explicit method has higher speedup and efficiency than the implicit method, but the time step of the implicit method can be enlarged, which saves CPU time as a whole.
