Abstract : This report describes the production of colour graphical output for the two dimensional finite difference reactive hydrocodes currently used by Weapons Systems Division. The programs use the NCAR graphics package and show how the careful choice appropriate colour schemes can significantly enhance the usefulness of the output from the finite difference codes. Application recent work in WSD are described, including simulation of the initiation of detonation in Composition B by bullet impact, and reignition of gaseous detonation following an abrupt area change. The report also discusses several ways in which a sequence of colour plots can be animated and then transferred to videotape, and a videotape sequence of the time dependent cellular structure of a gaseous detonation front was made to illustrate the implementation of the recommended procedure. Now that the capabilities of the software have been fully demonstrated these colour graphical and video techniques will be used on Service Sponsored Tasks to more effectively communicate the results and outcomes to the sponsors.
