Hello :-)
I build a model with basic_net which only contains
h1,h2,he3,he4,c12,n14,o16,ne20,mg24,si28. Then I start with this model
with a new net: 17_to_fe56.net, which contains more isotopes; I ask mesa
to print out all the number densities of all the isotopes and get for the
first model:
1 h1 1.15916837589503915E-082
2 he3 3.86389458631679743E-083
3 he4 11003654221746692.
4 c12 4913366122531561.0
5 n14 3.64066759934924061E-006
6 o16 634892493427121.88
7 ne20 106278142633425.97
8 mg24 16572243538063.971
9 si28 2389408021296.6865
10 s32 1405365066949.6206
11 ar36 244287953899.39539
12 ca40 170139322968.39069
13 ti44 2.63447358157960714E-084
14 cr48 2.41493411644797325E-084
15 fe52 2.22916995364428296E-084
16 fe56 2370992745057.8062
17 ni56 2.06994352838397713E-084
I expect the new isotopes just added (from number 10: s32 to number 17:
ni56) should be almost zero for the first model. But you can see that
s32,ar36,ca40 and fe56 just SUDDENLY appear. Why is that?
Thank you so much !
Sincerely,
Jing
