[Mesa-users] Help:Regarding extras routine error

[Thomas Steindl]

Dear ABHIJNAN,

It does seem to me like you have attached the wrong version of the run_star_extras file to this mail. 

Independent, it seems like your subroutine does not match the variables MESA is expecting.  mesa-r21.12.1/star/other shows that it other wind expects a function of the form subroutine null_other_wind(id, Lsurf, Msurf, Rsurf, Tsurf, X, Y, Z, w, ierr) while you are providing a function of the form subroutine pulsar_evaporation_wind(id, Lsurf, Msurf, Rsurf, Tsurf, w, ierr). As you can see, yours is missing the input variables X, Y, and Z. This should explain the error you are receiving.

That said, I find your run_star_extras looks like its missing some typical functions such as extras_startup, extras_start_step etc. I have no experience with the binary module in MESA, but since you are looking to evolve a binary, you might want look into run_binary_extras instead of run_star_extras. 

Best, Thomas
