[Mesa-users] Parameters for make_co_wd with higher initial mass (4M+)

[Evan Bauer]

Hi Tyler,

What MESA version are you using? This test case does struggle for more massive WDs in r21.12.1. I added a few changes since the latest public release that seem to help it for more massive WDs, but those changes haven’t been included in a public release yet. Here’s a summary of the commit:
https://github.com/MESAHub/mesa/commit/0a955404ffd00164e3bf354a58afa6a4882e4f6e <https://github.com/MESAHub/mesa/commit/0a955404ffd00164e3bf354a58afa6a4882e4f6e>

If you include those changes in your inlists, does it resolve the problem?

Cheers,
Evan

When reaching an initial mass of 4M, the time step for the calculations drop to a very low amount, and it takes an excessive number of models to get to the final luminosity value. The only parameter from the common inlist that was changed was the initial mass, but I’m assuming there might be other parameters that need to be changed.
