[Mesa-users] Problems implementig a new EOS

[Warrick Ball]

Hi Nuno,

I've been following the function calls for `other_eosPT` in r12778 and it looks like `other_eosPT` will be called if you set both `use_other_eos` in `&controls` and

     change_lnPgas_flag = .true.
     change_initial_lnPgas_flag = .true.
     new_lnPgas_flag = .true.

in `&star_job`.  Have you tried something like that?  Did it work?  If it produced and error, what was the error?

Cheers,
Warrick
