In order to understand our own origins we need to understand how the elements which make up our planet and our own bodies are created and distributed throughout the Galaxy. Understanding the starburst process is a vital part of this endeavor. A starburst galaxy is one in which a large number of massive stars form relatively close together in time and space. This leads, after a short time (a few million years), to a burst of supernovae (SN) physically close to one another. The result is an overlapping wake of explosive energy which drives into the galactic background mechanically reshaping it and enriching it with heavy elements. The cooler, denser, ambient Inter Stellar Medium (ISM) is swept-up and carried along by the hotter SN-ejecta . The theoretical treatment of all the interacting processes of the starburst requires computer simulation. We are using a 3D parallel version of the VH-1 hydrodynamics code to model starburst galaxies on our departments newly constructed 16 processor Linux cluster.. The code models hydrodynamics, gravity, and radiative cooling. A mass/energy distributions based on observations is used. The results of this model will be used to create visible and X-Ray spectra for comparison with observations from the Chandra and Hubble space telescopes. Preliminary results will be reported from simulations currently underway.
