Summary and status information during the evolution of stars is written to stdout; how much is written depends upon the value of the --quiet program option.

Detailed information is written to log files (described below). All COMPAS output files are created inside a container directory, specified by the --output-container program option.

If detailed output log files are created (see the --detailed-output program option), they will be created inside a containing directory named Detailed_Output within the COMPAS output container directory.

Also created in the COMPAS container directory is a file named Run_Details in which COMPAS records some details of the run (COMPAS version, start time, command line program option values etc.). Note that the option values recorded in the Run details file are the values specified on the command line, not the values specified in a grid file (if used).
