Sudipta What is the size of the simulation domain? At which radius do you evaluate the angular momentum? What is the spatial resolution there? What is the time resolution there? Is there any matter nearby? What happens if you change the evaluation radius? What if you make it smaller or larger? How close is this to the outer boundary? Do you have a visualisation of the geometry (e.g. the imaginary part of the Weyl scalar Psi_2)? In which direction does the angular momentum point? Does this change over time? What is the magnitude of the angular momentum? How does this compare to the mass?
