Dual Time Stepping Method

September 22, 1999, 08:12

Can somebody name some references for dual time stepping method? I am not satisfied with our present dual time stepping method of Jameson (1991). It produeced sometimes unphysical solutions, e.g., the temperature goes down and is too low.

As I have investigted further this problem of unphysical solution, I am beginning to know that this problem does not come directly from the dual-time stepping method but from the oscillation caused by the numerical scheme under large real time step. I thank the friends of the CFD community who gave me help after I issued my message describing this problem.
