atom sorting bin size 0 and Fene potential

Oh, if I use a special_bond lj 0 0 1
Do I need to use a pair style again?
I get the same error but when I add a coul/ cut the code is fine

this doesn't make much sense to me. the special_bond setting is very
different from defining a pair_style.
without a pair_style atoms in different molecules will not "see" each other.

it is very difficult to discuss such matters with only fragmented
knowledge of your inputs.
my guess is that you would be indeed defining a pair style in this case.
however, using only coul/cut by itself will likely produce bogus
results and crashes.

perhaps you should first try a simpler simulation without any bonds at
all and see, if you can get that to work correctly and producing
correct results.

Yes, you are right like always.thanks
