[Mesa-users] The problem of Laminar Flame Speeds in Degenerate Oxygen–Neon Mixtures

[Liguo]

Dear Rob
Thank you for your reply!
I also realize that this error means nuclear networks are too large .But in star/test_suit/conductive_flame,it can run with mesa_495.net.So I think that it will run successfully in star/test_suit/c13_pocket.Should I add other sentences in inlist file to run it successfully?


Sincerely!
Liguo

This is a fundamental problem with MESA that happens when running very large nuclear networks. The only solution is to run with a smaller nuclear network.

Dear professors
I taped  a word wrong in last email.Both in conductive_flame and c13_pocket,I wrote 'change_net=.true. new_net_name ='mesa_495.net' '.

Sincerely！

Hi
Changing the net to have 3335 isotopes is unlikely to run, MESA will almost certainly crash given the huge number of isotopes in that net.

Given you seem to have problems running the 495 net, I would suggest trying to get that working first before trying to go any bigger.

Repeating Aaron's question, What does "can't run successfully" mean? Are there any error messages? Do the results not look like what you expect, if so what do they look like and what do you expect?

Dear Timmes
Thank you very much for your reply and the reference you provided me!
If I change net in star job  to big net such as mesa_3335.net,whether should I add other sentences into inlist to run 'conductive_flame' successfully in star/test_suit?

Sincerely!
Liguo
