Abstract: This report documents the U.S. Army Research Laboratory Gun Tube Erosion Code (ATEC) user input as well as output from the code. Instructions for developing an input deck are explicitly provided to assist the user. Each input variable is described, and units are provided where necessary. The appendices include examples of various input decks and an example of the species input file. Files required to operate the code include a user-generated input deck, an output file HTEMP.OUT from XKTC (Gough, P. S. "The XNOVAKTC Code." BRL-CR-627, U.S. Army Ballistic Research Laboratory, Aberdeen Proving Ground, MD, 1990), the NASA Lewis library (Gordon, S., and B. J. McBride. "Computer Program for Calculation of Complex Chemical Equilibrium Compositions, Rocket Performance, Incident and Reflected Shocks, and Chapman-Jouget Detonations." NASA SP- 273, NASA Lewis, Cleveland, OH, 1971), and a species temporal file, "species.out", from a coupled interballistic equilibrium thermodynamic code. The ATEC code has been applied to the 25-mm Bushmaster cannon, Navy 5-in cannons, the 120-mm M256 tank cannon, as well as various vented fixtures, and has performed well in representing the physics which occurs at the surface.
