[mesa-users] He-flash problem

[Jakub Ostrowski]

Hi!

I'm a new user of MESA and I'm currently trying to learn how to use the code. It's totally awesome :) However I found a problem with helium flash. I try to calculate evolution of 1.0 M_S star and it doesn't want to start helium burning.

I tried many inlists with different parameters but nothing helps. I'm especially bothered because even the unmodified be me inlist from test '1M_pre_ms_to_wd' doesn't work. I calculated up to 10500 models and then forced stop. In awesome video '1M summary', which is available on the main page of MESA, there is a helium flash around model 4500.

I don't have problem with helium burning in massive models without He-flash. I tested eg. 7 or 20 solar masses.

I use OS X 10.8.2, MESA 4631 and the latest version of SDK. Because I'm really a beginning user I don't know which other information I should provide you in order to solve this problem.

I would be grateful for any kind of help.

 Cheers,
Jakub

PS. Is it possible to use with PGSTAR the same format of output during calculations of evolution like in the mentioned video? I think it has perfect size and optimal set of parameters just to follow what the code is doing.
