CE analysis is a free and open source tool to generate simple analysis of common envelope simulations generated in the hydro 3D code Phantom created by Daniel J Price.
Data is read directly from the snapshots files (written in binary and with Big Endian format) using the Python3 module sarracen to create plots of global quantities, such as orbital separation and porcentage of ejected envelope.
CE analysis uses the SPH smoothing kernel to calculate physical quantities, giving a proper representation of the data. The goal is to produce nice plots and visualisations from the SPH output.
CE analysis also generates ascii files corresponding to the created plots.
More information can be found in CE_analysis documentation page
In the terminal, from the CE_analysis main directory, type:
sudo make install
to install all python required modules and latex fonts for the plots
We include a simple test to check if the code has being installed successfully. This test will use a CE simulation dumpfiles from data/CE_example (if this files are not stored in that directory it will download them, a free space of 5 GB is required for this). The test will create plots of orbital evolution of the binary and mechanical energy of the envelope. To run this test type in the main CE_analysis directory:
make test
At the end of the test CE_analysis will confirm the files are saved in the figs directory.
From the main CE_analysis directory, type
python3 src/energies.py CE_DIR CE_figs
to use the dumpfiles stored in CE_DIR directory to generate the mechanical energy plot in CE_figs.
Type:
python3 src/separation.py CE_DIR CE_figs
to create the separation plots. If CE_figs is not given, the plots will be saved in CE_DIR/figs/
