摘要: 针对二维三温耦合热传导差分方程组的特点,给出并比较了块GS算法和ICCG算法.数值结果表明,ICCG算法的收敛速度比块GS算法的收敛速度可以快数千倍.并且,在二维激光黑腔靶耦合的数值计算中,如果能够实现向量化计算,使用ICCG方法将会大大提高数值模拟的计算效率.

Abstract: In view of the special needs for systems of difference equations of 2-D heat conduction coupled three temperature,the block G-S algorithm and the ICCG algorithm are presented and compared.Numerical results show that the ICCG algorithm is thousands times faster than the block G-S algorithm.Furthermore,in 2-D numerical simulation of laser hohlraum target coupling,the ICCG algorithm will raise greatly computational efficiency if it can realize vectorzation operation.

Key words: 2-D heat conduction coupled three temperature, block G-S algorithm, ICCG algori
