[mesa-users] hd.h5 files

[Falk Herwig]

Sorry for this answer being relatively delayed. Indeed, as Sam pointed out, the se.h5 output option allows you to write profiles of relevant quantities for each time step into hdf5 files, in a structured way that was designed to allow nucleosynthesis post-processing with the NuGrid mppnp code. I understand that se is support by MESA_sdk, but standalone versions can be downloaded also from 

http://www.astro.keele.ac.uk/nugrid/releases-and-software-downloads

and that is what should work as well (at least it does for me and some others).

We are working on making se output more flexible in the near future, similar to controlling output through the log_columns.list file, for example.   However, presently what is written out depends on what is hard coded in star/public.se_support.f and an easy way to generate an error is to ask writing species that don't exist in the chosen network. But this should be fixed soon. In the meantime se output is still experimental. However, if you have a project that may require full-blown nucleosynthesis analysis, consider contacting a NuGrid collaborator and provide her or him with some se files. This works now very well.

An example for an se.input file is here:

&sehead
        codev='copiapo.phys.UVic.CA:/rpod2/fherwig/MESA/mesa6:r3372'
        modname='M15.0Z0.02'
        prefix='MZ'
/

where codev is some string saying what you want to save as an hdf5 header attribute concerning the code version, mod name is your internal model sequence identifier, and prefix is the prefix for the se.h5 output files. By default 1000 cycles go into one h5 file. The number in the file name is the number of the first cycle in the file. MESA will attempt to save the files into a directory with the string specified in 
modname. We usually generate these se.input files automatically as part of the run scripts.

Best, Falk.
