摘要

YT是一個廣泛應用於天文物理模擬以及資料分析的繪圖分析軟體。YT亦是一個設計給高解析度自適性網格模擬程式的整合平台。在我們的研究中，我們利用HDF5 (Hierarchy Data Format 5) 的檔案格式，先設計出我們實驗室的GAMER (daptive mesh refinement code with graphics-processing-unit acceleration自適性網格模擬程式) 對YT的整合接面。 此外在輸入輸出上亦採用平行設計。最後，我們利用YT分析了幾種不同的模擬結果，1)暗物質 2)活躍星系核 3)恆星形成 4)磁流體。

YT is a visualization and data analysis software widely used in astrophysics, which provides an integrated platform for various multi-resolution simulation codes. In our study, we first construct our GAMER (adaptive mesh refinement code with graphics-processing-unit acceleration) front-end interface for YT, where HDF5 (Hierarchy Data Format 5) format is adopted to improve parallel data I/O and data portability. Finally, we apply YT to analyze four different simulation data sets: 1) cosmological structure formation of the wave dark matter, and 2) interactive jets from active galactic nucleus (AGNs) 3) star formation 4) magnetic hydrodynamics (MHD).
