Astrophysics is an extension of classical Astronomy and physics, which concerns with the physical nature of stars and other celestial bodies. Computational astrophysics is that the numerical methods to unravel the issues in astrophysics on a computer. In this panel discussion with the industrial Professionals give an out frame of the Cosmological computer simulations of galaxy formation which act as the primary tool to study the structure emergence in the Universe. This session describes the main techniques of such stimulations and their application to develop and constrain galaxy formation theories.
