Abstract: The research progress of the Godunov type explicit large time step scheme is reviewed. Firstly, the concept, classifications and advantages of explicit large time step scheme are introduced. Then, followed by its construction methods, higher order accuracy extension approaches, multi-dimension generalization methods, and characteristics analysis including stability, resolution and computational efficiency. Finally, further development direction of the Godunov type explicit large time step scheme is proposed.

Key words: large time step schemes, Godunov type schemes, highly efficient algorithm, scheme stability, explicit schemes
