Need help with 1D Euler Code, using ECUSP
 

Hello! If anyone could've helped me with 1D Euler Code, using ECUSP splitting, that would be great. The code in CPP is here: http://cfd-posts.narod.ru/Euler1D.cpp

The shock tube breaks with sea-saw oscillations. I suspect there's a error in temporal scheme, but i can't find it.

Thank you!
