History of CFD-MHD initiative

CFD-MHD (changed into CompAS, in Feb. 2012, for Computational Astrophysics) initiative has been a joint research project of the Institute of Astronomy and Astrophysics (ASIAA) and the Institute of Mathematics (ASIM) of the Academia Sinica, and the Department of Mathematics of the National Taiwan University. Its main goal is to develop high-performance codes of computational fluid dynamics and magnetohydrodynamics (CFD-MHD) for astrophysical problems.

We have successfully developed a set of 2-D/3-D Godunov codes based on exact/approximate Reimann solver. They are featured with self-gravitation and characteristics decomposition on the boundary, guaranteed non-reflection. At present we are applying these codes to the study of two main problems: the structure and evolution of gas disks in spiral galaxies and the planet migration in protostellar disks.

• The structure and evolution of gas disks in galaxies
• The structure and evolution of protostellar disks
• Computational Fluid Dynamics
• Simulation of Collapse of Magnetic Molecular Cloud
• Zeus 2D Simulations of Wide-angle winds
• Radio Free-Free Emissions from YSO Jets
• HST Observations of Jets
• Meteorites and Origins of Solar System
• Simulation of Bar-driven Spirals in Galactic Disks
• The Structure and Evolution of the Inner Gas-dust Disk of nearby Spiral Galaxies
