Abstract: A new type of hybrid iterative method is presented, which is competent in solving the large scale sparse linear systems derived from the 2-dimensional 3-temperature radiation dynamic energy equations. Numerical results show that the new method is as 4 times fast as the old ones.Especially on the cases the old one doesn't converge, the new method can easily get the solution to the precision required. It can successfully complete the simulation and the final physical parameters of the simulation coincide with the theory.

Key words: two-dimensional three-temperature energy equations, hybrid method
