Compile environment

  • Linux/Unix: gcc, glibc, MATLAB/Octave
    • Compile in 'src/hydrocode_2D': Run './hydrocode.sh' command on the terminal.
  • Winodws: Visual Studio, MATLAB/Octave
    • Create a C++ Project from Existing Code in 'src/hydrocode_2D/' with ProjectName 'hydrocode'.
    • Compile in 'x64/Debug' using shortcut key 'Ctrl+B' with Visual Studio.

Usage description

  • Input files are stored in folder 'data_in/two-dim/name_of_test_example/'.
  • Input files may be produced by MATLAB/Octave script 'value_start.m'.
  • Description of configuration file 'config.txt/.dat' refers to 'doc/config.csv'.
  • Run program:
    • Linux/Unix: Run 'shell/hydrocode_run.sh' command on the terminal.
      The details are as follows:
      Run 'hydrocode.out name_of_test_example name_of_numeric_result order[_scheme] coordinate config[n]=(double)C' command on the terminal.
      e.g. 'hydrocode.out GRP_Book/6_1 GRP_Book/6_1 2[_GRP] EUL 5=100' (second-order Eulerian GRP scheme).
      • order: Order of numerical scheme (= 1 or 2).
      • scheme: Scheme name (= Riemann_exact/Godunov, GRP or …).
      • coordinate: Eulerian coordinate framework (= EUL).
    • Windows: Run 'hydrocode.bat' command on the terminal.
      The details are as follows:
      Run 'hydrocode.exe name_of_test_example name_of_numeric_result order[_scheme] coordinate n=C' command on the terminal.
