[Mesa-users] Relaxing compositions - new profiles

[Benjamin Fernando]

Hi,

I am working with v. 10398 on relaxing the composition profiles of dwarf stars using the relax_initial_composition option. However, I cannot figure out why some of the input files work and others do not:

Attached are two (identical in content but with different filenames). The first, “lambda_bootis_relax” works fine, but the second “lambda_bootis_relax_2” gives the following error:

change to approx21.net
 number of species          21

                              relax_initial_composition
failed while trying to read 1st line of lambda_bootis_relax_2
 do_relax_initial_composition ierr        5010
 do_star_job_controls_after ierr        5010
 before_evolve_loop ierr        5010

As far as I can tell they are identical (I’m not actually trying to use two different files to do the same thing, but this is the simplest example to illustrate this that I could make). I’m wondering whether it might be something to do with the input file format? Apologies if I am missing something obvious! Inlist is below, model attached.


Thanks
Ben
