Hydrodynamical simulations using a fully threaded tree Original Research Article

We developed a 3D code of Adaptive Mesh Refinement (AMR) hydrodynamical simulations that is useful for propagations of an interplanetary shock wave. In this code, we adopted the Fully Threaded Tree (FTT; Khokhlov 1998) for AMR part, the 3rd order MUSCL of the Roe method for hydrodynamical part, and the two step method for the 2nd order time development. In this article, we explain our 3D AMR code and the FTT, and report some results of test calculation.
