[mesa-users] how to create a ZAMS model?

[João Faria]

Hi!

Jakub, I think the example called *create_zams* in the test_suite might 
be what you're looking for.

I have tried to use stop_at_zams = .true. before and it didn't work as 
well. I now understand why from Josiah's explanation. But, is it just me 
or the documentation in controls.default is somewhat confusing? I would 
think that "don't independently apply" would mean "don't set these:"
