Does anyone have FV WENO code for 1D Euler Equation?

Hello Everyone,

Recently, I have been working on the FV WENO code with RK3. I followed the steps in Prof Shu's paper. However, when applied to shock tube problem, oscillation generate in the program. I have checked every step for many times but still can't find the bug. Can anyone give me a sample code it? I will be greatly appreciated.

Thanks a lot.

branch -> characteristic FV

Component-wise solution can give some oscillations so you should opt for a characteristic wise solution.
For 1d, FD or FV doesn't have any difference in performance/ accuracy though
