[Carpetx-developers] Carpetx-developers Digest, Vol 7, Issue 4

[Bruno Giacomazzo]

Hi Jay,
   thanks for the plots.

   In the 10 point case it seems that you are using a lower number of
points in Spritz than GRHydroX. In Spritz's plot we see indeed the boundary
conditions (and the points start after x=-0.5).

  When using 100 points, GRHydroX seems to overestimate the density at the
contact discontinuity, but otherwise it looks fine.

Cheers,
Bruno
