Scientific paper

The authors present a two-dimensional hydrodynamic code suited to study astrophysical flows in many different environments. The code solves the hydrodynamic equations in conservative form in the most used coordinate systems and is based on an explicit fully two-dimensional flux corrected transport (FCT) technique, which ensures an accurate description of steep gradient regions and shocks, a relatively ample flexibility to include a variety of physical effects, and a good efficiency for speed on vector or array processors. Extensive testing has allowed an accurate "tuning" of the FCT numerical parameters. This code is among the best FCT codes and performs well in a whole set of demanding strongly nonlinear hydrodynamic tests, getting close to performances of more complex codes, while remaining less computationally expensive and more than sufficient for most astrophysical applications.
