fix bond/create

fix bond create the cut off is 7.6 but your pairwise cutoff is 1.12 ?

Rmin must be <= the pairwise cutoff distance between itype and jtype atoms, as defined by the pair_style command”

fix bond/create creates bonds based on the neighbour list which depends on the pairwise cutoff
I am not sure whether the fix bond/create is creating bonds in your case.


In lj/expand, actual cutoff is (cutoff) + (delta).
In my case, actual cutoff is 1.12 + 6.5 = 7.62.

So Rmin(=7.6) < actual cutoff (7.62).
