Nakamura T. et al. (2022), Science This document describes about the files related to 3D SPH simulations. Contact information: Hidenori Genda, Earth-Life Science Institute, Tokyo Institute of Technology E-mail: genda@elsi.jp --------------------------------------------------------------------------------------- SPH simulations: (1) Use Makefile for compiling in "Program_SPH_Code" - need gfortran and OpenMP - The number of CPU cores that you use can be changed in "N_TRD" in "Mod_Parameter.f90". (2) Get the excution file "Main_SPH.out" (3) Move "Main_SPH.out" to an any working directory. (4) Copy an initial condition file "initial.dat" in "Files_for_Initial_Conditions" to the working directory (5) Excute "Main_SPH.out" (6) Get data for snapshots in "DATA_PTCL" (defalt: 500 snapshots) Clump Finding analysis: (1) Use Makefile for compiling in "Program_Clump_Finding" (2) Get the excution file "calc" (3) Move "calc" to the working directory, and excute it.
