Hi Tim, Thanks for reporting. The issue was that gamma is assumed to be read from the dump file, but in your case gamma is not present in the data and so was defaulting to zero.
To fix this I’ve added a prompt to set gamma manually: enter density of ambient medium ([0.000:], default=1.000): enter blast wave energy E ([0.000:], default=0.8511): set adiabatic gamma manually? (no=read from dumps) (default=no): y enter gamma (default=1.667): Now fixed: r5251 (svn up to get the latest; I’m overdue a release so will push a new version shortly also) Daniel PS: As a workaround with older versions of splash, you can also set gamma for the ascii read using an environment variable: export ASPLASH_GAMMAVAL=1.666667 > On 24 Jul 2015, at 3:35 am, [email protected] wrote: > > Hi, > > I have an ascii snapshot with SPH data (1st line is time) of a Sedov test > with columns > y > z > vx > vy > vz > mass > h > rho > u > > as well as a corresponding analytic solution file with the 1st column radius > and 2nd density.
