Running detailed output

The COMPAS run from the tutorial creates a new directory COMPAS_Output, inside which you will find the following files/directories (here we assume logfile_type = 'HDF5' in the python submit file):

Run_Details
A record of the COMPAS command-line program options specified for this tutorial (these are the values set by compasConfigDefault.yaml when using runSubmit.py, or the COMPAS default values if not executing via runSubmit.py).

COMPAS_Output.h5
The primary output file, containing HDF5 data groups for the relevant output physics. By default, and for a sufficiently large simulation, this will include:

  • BSE_Common_Envelopes

  • BSE_Double_Compact_Objects

  • BSE_RLOF

  • BSE_Supernovae

  • BSE_System_Parameters

Detailed_Output
This directory contains the detailed output file, BSE_Detailed_Output_0.h5, which records the detailed time evolution of binary. This file, and directory, is only produced if detailed_output = True in the python submit file.

We examine BSE_Detailed_Output_0.h5 to look at the evolution of the two stars. A default python plotting script has been included to visualise the data. Let's run the script:

python3 plot_detailed_evolution.py

This should produce a plot similar to Figure 5:

COMPAS provides many tools for analysing and post-processing the data - see Post-processing tools for more details.
