On Conditions of Iteration Method with Two Optimal Relaxation Factors

TANG Yong-jian1, XIANG Long-wan2 (1. Dept. of Basic Science, Shanghai University of Electric Power, Shanghai 200090, China; 2. Dept. Appl. Math, Shanghai Jiaotong University, Shanghai 200030, China)  
For a large scale linear equations AX = b, if A has form as ,this paper proves that using two relaxation factors would be better than conventional SOR iteration with single relaxation factor under some conditions. Some examples show the effectiveness of the scheme. The authors used two relaxation factors to calculate the 3D steady temperature distribution in a hydrogen inner-cooled turbogenerator rotor and got very good results.
