Hi all,

I am trying to make a shock tube, hence 1D Euler equations, which I solve using SUPG. I have troubles understanding how shock capturing terms are calculated. The SUPG formulation I use is correct, as the test case with expansion fans only is solved correct. I tried the \delta_{91} and Y Z \beta, but for both I'm not understanding how they work. I believe in the end it should be a 3x3 diagonal matrix.

Any help would be extremely appreciated.
