[mesa-users] element diffusion during core he burning phase

[Bill Paxton]

Hi Ehsan,

I'd like to check this with my current development version, but I can't use the photo from the older version.
Please save a model from about the same time as the photo and send that.
(photos are specific to a particular version; saved models are not.)

Thanks,
Bill

This happens when core he drops below ~0.90, and the model number is almost 1599. I have also attached a restart photo.
