Using F4 Tally on Hexagonal Lattice Geometry

[gvntr52]

How can i use F4 tally in hexagonal lattice geometry which composed of circular fuel assembly? For example one hexagonal lattice includes circle which is cell number 5 and another hexagonal lattice includes circle which is cell number 7 etc. I want to use all these cells in one f4 tally.
Please help
Many thanks...

Do you want a separate tally bin for each cell or an average f4 tally for the same cell over all the lattice locations?

I want to average f4 tally for the same cell

 

[quarkle]

In that case its as straightforward as:

F4:N (5<L1) (7<L2)
Where L1 and L2 are the lattice numbers where cells 5 and 7 are located.​

If you want an average flux for all cells 5 and 7 all over the geometry it'll be:

F4:N (5 7)​
