[mesa-users] Segmentation fault on the main sequence with a 1.2M star

[Earl Bellinger]

Hello mesa users,

I am using the newest version of mesa, r8118. I'm using an Eddington
atmosphere, step overshooting, and inhibited diffusion. My inlist and the
zams model I'm starting from is attached.

I am getting the following error:


 tried to increase number of mesh points beyond max allowed nz       20000

 mesh_plan problem
 doing mesh_call_number         832
 s% model_number        1749

 failed in do_mesh

Program received signal SIGSEGV: Segmentation fault - invalid memory
reference.

./rn: line 10: 22516 Segmentation fault      ./star


This seems to crop up in about 0.5% of the runs that I am doing. Any
advice?

Thanks,
