The Computational Astrophysics Group aims at developing a next-generation hydro simulation code for the studies from cosmic structure formation to interstellar medium and star formation.  This group is organized by a few Korean scientists distributed from universities to institutes and many graduate students are currently involved. Even though most members are working on diverse fields of astrophysics, we are planning to develop numerical techiniques for the gas dynamics which are common in most fields of astrophysics. This challenging work was first inititated by Professor Changbom Park at Korea Institute for Advanced Study in the mid 2006  and promptly echoed by various researchers whose primary interests are interstellar medium (Prof. Seung-Soo Hong, Prof. Jungyeon Jo, Dr. Jongsoo Kim, Dr. SangMin Lee, and Prof. Woong-Tae Kim) and the Large-scale Structures (Dr. Juhan Kim).

 These days, we are surveying the cutting-edge hydro techniques applied in various fields of interests in engineerings (aerodynamics). Also, we have one of the fastest and most efficient N-body codes (N-body Code for Astrophysical Problems: NCAP) but we would not restrict the forth-coming hydro code to the internal structure of the NCAP. We are studying various implementations of possible hydro code to the gravity code.

 Upto now, there have been five group meetings on various topics of numerical issues such as Smoothed-Particle and Mesh-based hydrodynamics, multi-time stepping, Voronoi Tessellation technique, N-Body6, and parallel programmings. Most of them are forming a groundwork for the hydrodynamics and are anticipated to guarantee the success of the group mission ultimately.
