comments

The version that we distribute is a subset of everything we've done
with the code. It does include 1D, 2D, 3D, 1D self-gravity, shock
flattening, spherical and cylindrical geometries, and angular
momentum. It does not include artificial viscosity, 2D or 3D
self-gravity, multiple fluids, a variable gamma equation of state, or
radiative heating or cooling. A large number of test case
initializations are included. We highly recommend that you be familiar
with numerical hydrodynamics before you attempt to use VH-1, or that
you plan on spending a large amount of time learning hydro before you
believe anything.
