We present a new geometrical approach to the study of accretion flows ontorotating (Kerr) black holes. Instead of Boyer-Lindquist coordinates, thestandard choice in all existing numerical simulations in the literature, weemploy the simplest example of a horizon adapted coordinate system, theKerr-Schild coordinates. This choice eliminates boundary ambiguities andunphysical divergent behavior at the event horizon. Computations of Bondi-Hoyleaccretion onto extreme Kerr black holes, performed here for the first time,demonstrate the key advantages of this procedure. We argue it offers the bestapproach to the numerical study of the, observationally, increasingly moreaccesible relativistic inner region around black holes.Comment: 15 pages, 2 figures, aasms4.sty, major changes regarding section names and style, accepted in ApJ Letter
