Yes. The way this is achieved is essentially that one constructs a TOV
solution with a particular EOS, which would make a stable star. One
then *evolves* with a different EOS (and a step in between to fix the
constraints by keeping the stress-energy tensor constant and adjusting
eg HydroBase::rho and HydroBase::press to achieve this).

First thing to do would be to check the density plot (I hope I have
one) that is in the GRHydro paper (Loeffler et al.).
