Re: Activity/fission/neutron balance binnings cannot be track-length

Dear Angelo,
If you want to find activity in a region of your geometry using USRBIN card,
you should use WHAT(1)=1.0 or you should use R-Phi-Z (Point) if you are using Flair.
Activity cannot be scored as a tracklength binning, but as point binning.
It ran successfully in my PC with changed WHAT(1)=1.0
Find attached the revised input and corresponding output file.

Hi to all,
i'm trying to calculate the activity in a region of my geometry but the code give me this error:

 *** Activity/fission/neutron balance binnings cannot be track-length!!!

what mean?
I attach my input file. Thank you to all for your help.
