Hi Mathieu, The main thing is to add isotopes before they become active in nuclear reactions. Ideally, everything would run so fast, you'd just dump them all in from the beginning. But that's still a distant dream for now, so you'll want to creep up on it instead. Start with a small-ish net and add isos as you move towards advanced burning. You can just do this by hand (that's what I did for the test cases). Or you can try using an "adaptive network" based on Alex Heger's scheme. For that option, take a look at the "adjust_net" test case.
