CMHOG2

cmhog2 is a continuation of the code developed by Piner, Stone and Teuben (see their paper Nuclear Rings and Mass Inflow in Hydrodynamic Simulations of Barred Galaxies in 1995ApJ...449..508P). A manual (under development, contact the authors for CVS access) describes later (2002/2003) additions, such as reading a grid potential derived from observations or models, as well as a bug uncovered in 2011 about a sign error in the azimuthal force .
