[Mesa-users] Binary evolution residual_norm warning for high masses

[Gökhan Yücel]

Hey everyone,

I have been trying to a basic binary evolution with both stars evolve
simultaneously. But I get warning and evolution slows to an extreme degree,
even it stops at the start of the evolution if I try to increase the mass
of any component more than 6 Msun.

I tried to increase tol_resuidual_norm and tol_max_residual parameters, but
it didn't work.
I know my inlist is basic for high mass evolutions, but I believe it
shouldn't give me this warning, considering my calculations don't even
reach to TAMS. I have attached the necessary files to re-produce the
warning.

Any help would be highly appreciated.

I'm using MESA version r23.05.1

Cheers,
Gökhan
