[Mesa-users] Problems implementig a new EOS

[Nuno Moedas]

Hi Warrick,

Thank you for your answer.
I have not tried the commands that you indicated in `&star_job`. Now it 
seems it is working and now MESA are using the eosPT instead of eosDT. 
For now, I was only testing with the current functions and tables that 
MESA already has. Now I will try to implement the eos tables that I have 
access to.

Once again thank you for your help.

Best Regards,
Nuno
