Thank you very much for your hint.
There is another strange problem, I change my RKDG to MOMOMIAL but I can
only
ran succesful when I use CONSTANT, SECOND and FOURTH basis, FIRST and THIRD
is unsteady, can your epplitic code works well with FIRST or THIRD?
It is so strange, when I use XYZ basis, CONSTANT and FIRST is OK but
SECOND can not
work.
I will change my implicit code to monomial later and connect you.
My code solve euler equation and I am trying to solve NS equaiton later.
Best Regards!
Luyi
