Hi,
For studying I coded the AUSM scheme for an 1-D Riemann problem. I found it shows oscillations on an non-uniform grid even with even 1st order spatial accuracy. Of course it gives non-oscillatory results when a uniform grid is adopted. Did I do something wrong? I already chose CFL number 0.5 for the smallest cell. |
