DISCUSSION AREA
Here is the principle about the best physical result a numerical scheme can provide under the cell resolution.
You are welcome to try these test cases if you have confidence on your higherorder schemes for the Euler equations.
CFD can go beyond numerical PDE. Traditional concepts of stability, consistency, and convergence need to be upgraded.
