Explicit RK time integration in SU2.!!! -- CFD Online Discussion Forums

January 7, 2015, 10:41	Explicit RK time integration in SU2.!!!	#1
Vino Senior Member Vino Join Date: Mar 2013 Posts: 130 Rep Power: 13	Hi, I would like to know what is the order of accuracy of the RK used in SU2. It uses three co-efficient, means three stage. If I want to make it even higher stage, say 4 stage, can I just add 4 co-efficient in config file.? or do I need to re-implement the RK in time_integration file? Also I would like to the implemented is the classical RK method, or Modified RK method (mainly for higher stability margin)? If possible, can I get the reference of the RK method implemented in SU2. Thank you.
