[mesa-users] Question about saving and using png/ps plots

[Willie Strickland]

I routinely use the following lines in the &star_job section of the inlist

  ! plot or not
    pgstar_flag = .true.
    save_pgstar_files_when_terminate = .true.

As has been mentioned, setting pgstar_flag = .false. will stop all output of onscreen plots.  I needed this setting when using a mesa installation on a remote supercomputer.  For some reason we could get pgstar to write out files to disk, but that particular installation would fail when trying to display live pgstar output.  It suited my needs to just display live output, so we did not troubleshoot the problem.

I like to save a set of plots routinely at the end of a run whether displaying them or not.  So with the above 2 settings both to true, and the following lines in my inlist_pgstar file, mesa will save up to five different final plots in the png directory when the run finishes.  I get an error if I try to save more than 5.

         HR_file_flag = .true.
         HR_file_cnt = 100000 ! set to large number to just save the last file
         TRho_Profile_file_flag = .true.
         TRho_Profile_file_cnt = 100000 ! set to large number to just save the last file
!         Grid1_file_flag = .true.
!         Grid1_file_cnt = 100000 ! set to large number to just save the last file
         Grid6_win_flag = .true.
         Grid6_file_flag = .true.
         Grid6_file_cnt = 100000 ! set to large number to just save the last file
	 Kipp_file_flag = .true.
         Kipp_file_cnt = 100000 ! set to large number to just save the last file
         Abundance_file_flag = .true.
         Abundance_file_cnt = 100000 ! set to large number to just save the last file

This allows me to review the end state after a run is finished or perhaps when going back to review the results of a previous run.
