Hello Hee Il, > I have encountered a bug in using HydroBase::temperature_evolution_method. > If it is given explicitly by taking its default value "GRHydro", my > runs crashed while reading a Lorene data.

The default value for HydroBase::temperature_evolution_method is "none" (see http://einsteintoolkit.org/thornguide/EinsteinBase/HydroBase/documentation.html#TBL-15-7-1) so not setting it explicitly is identical to setting it to "none".

Can you provide the full log output (and ideally a parfile to reproduce the issue) for stdout and stderr as well as any backtract.X.txt files created? If it crashes with a SEGFAULT or similar that would indeed be a bug. Note that most of the LORENE data has been used with equations of state that do not use temperature (usually tabulated ones only) so if you are using one of LORENE's sample data sets and set this parameter then even if the code apparently succeeds the evolution may not be correct or what you expect.
