[Mesa-users] problem of ccsn_llp

[游凱安]

Dear professors,

I have trouble running ccsn_llp.

Usually I put the "final.mod" from make_pre_ccsn to the ccsn_llp.

the initial mass of "final.mod" is 20m.

However, I have tried various masses before,

and I know the problem usually occur in part_edep due to these factor are
not big enough.

max_age_in_seconds
total_mass_for_inject_extra_ergs_sec

but this  time the fail message is quite weird.

stopping because of problems dt < min_timestep_limit
terminated evolution: cannot find acceptable model

it stop after finishing part_edep and only run few steps in part1.

I have retry make_pre_ccsn before and still not success.

but I have tried the others model and they still can work.

how can I fix the problem?

Thanks for your help and patience.
