Description
Summary:Main changes in this update include: Add an implementation of a shooting method for finding MOT(O)S (see the new tutorial on the shooting method) Enable the representation (and search) of toroidal MOTSs Implement predicting the MOTS location by tracking either the north pole, south pole, locally minimal x-location (useful for neck-like features) and coordinate center (default) Smaller changes: Add a smarter line search. To use it, add the step_mult="auto" option to the find_mots() call (or to the configuration object). New example metric for a slice of Schwarzschild in Painleve-Gullstrand coordinates Make computing properties more robust for initial data Allow most properties to be computed for toroidal MOTSs New MOTS properties: "ricci_difference_integral" , "ricci_interp" (see the documentation of the axisym.trackmots.props.compute_props() function for details) New MOTT properties via functions of the form "compute_*" in module axisym.trackmots.props Optionally save all interim Newton steps Many small ...
