Computer simulations provide us a powerful tool to reveal the formation processes of many astronomical objects, such as the formation of large-scale structure, galaxies, and stars, which are impossible to be observed directly. The sophisticated numerical simulations including relevant physics open a window to study the evolution of these objects. Therefore, we introduce a massively-parallel, and multi-physics code, GIZMO by demonstrating its astrophysical applications. In this poster, I present the simulations of the formation of an isolated disk galaxy with GIZMO. Due to the complexity of data, I use ParaView and SPLASH to perform the data visualization and compare my results with observational data to study the galaxy formation. Finally, I will also point out the challenges of modern cosmological simulations and mention my future work.
