Hallo Einsteintoolkit-Community,

i'm a phd-student in my first year at University zu Kiel, Germany. I've read many papers and saw the Toolkit for simulating relativistic hydrodynamics at black holes. First i have some important qustions and hope you can help me.

Does the BSSN-algorithm regard the hydrodynamic mass as source function in the current timestep to calculate the hypersurface of the next timestep? Does this work via the TmunuBase? Is the self-gravitation of the hydrodynamics calculated by the perturbation of the spacetime?

I hope you can help me, thank you very much.
