[Mesa-users] Models failing to reach core collapse

[Dan Patnaude]

Hi Bill-

Sorry, you misunderstood me. I'm happy to go this route. I just need to do
a comparison of the various settings between the example case and what I
had used in the past, in order to see where the differences are, and then
try to understand them. I'm sorry if you misunderstood my response.

Best,
Dan
