[mesa-users] change_net

[jingluan at caltech.edu]

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
