Dear forum,
I am running some activation simulations with FISPACT-II.
Unfortunately, I am struggling with the following simulation when I try to impose UNCERTAINTY 2 to have a complete path analysis (by the way using UNCERTAINTY 0 it works).
https://user.iter.org/filesharing/?uid= ... 3f4fb44324
Looking into the log files seems that some reaction channel is missing, right? Should I populate the pathways? How?
I hope you can help on this.
Thanks in advance,
All the best,
Marco

Re: UNCERTAINTY Calculation
Dear Marco,
FISPACT-II adds data to the pathways analysis when one of the solver-initation keywords (ATOMS, SPECTRUM or STEP) are used. In this simulation the various irradiation steps do not have any of these keywords and the first case has 0 flux:
This results in the code attempting to handle pathways where there are no reactions, causing an error. To solve this simply add in one of those keywords during the irradiation steps, such as:
Let me know if this works for you.
Best regards,
Michael
