mesa-users] Hydro convergence failure at end of main sequence.

[Sam Jones]

Hi all,

I am using MESA version 2664 (compiled with ifortran 11.1) on Ubuntu 
10.04 to run a 20Mo model up to collapse, but at the end of the main 
sequence I get an error "hydro_failed_to_converge". I have tried this 
with two different timestep parameters and attach the inlists for both 
runs - maybe these values for varcontrol are inappropriate?

As you can see from the inlists, I am also using the Dutch RGB and AGB 
wind scheme but there is no mass loss on the main sequence - is there a 
parameter for this?

Attached also is a Kippenhahn diagram of one of the runs.

Thanks in advance for any help!
Sam.
