Compile environment
- Linux/Unix: g++, glibc++, MATLAB/Octave
- Compile in 'src/hydrocode_Radial_Lag': Run './hydrocode.sh' command on the terminal.
- Winodws: Visual Studio, MATLAB/Octave
- Create a C++ Project from Existing Code in 'src/hydrocode_Radial_Lag/' 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/one-dim/Radial_Symmetry/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] dim config[n]=(double)C' command on the terminal.
e.g. 'hydrocode.out Radial_Symmetry/Two_Component/A3_shell Radial_Symmetry/Two_Component/A3_shell 2[_GRP] 2 42=-2' (second-order Lagrangian GRP scheme).
- order: Order of numerical scheme (= 1 or 2).
- scheme: Scheme name (= Riemann_exact/Godunov, GRP or …).
- dim: Spatial dimension number (= 2).
- 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] dim n=C' command on the terminal.
