Dear MESA Users,
I have been evolving AGB stars to the end of the TP-AGB stage and am now trying to evolve them off the AGB and to the white dwarf cooling track. Unfortunately, I am finding the post-AGB evolution to be very slow (it is taking about 140,000 models to go from logTeff = 3.56 to 3.63). So, I am trying to figure out what is limiting the timestep as there is very little change in the structure variables. The terminal output for dt_limit often says "max increase", but this is not listed in the table for dt_limit in controls.defaults. Does anyone know what this means and/or have any tips for faster post-AGB evolution?
Thanks,
Natalie Rees
