neighbor_modify command

Dear Lammpsers,

I am using AlO.eam.alloy as the pair_coefficient and I am facing with this error:
neighbor list overflow, boost neighbor_modify one

which type of neighbor_modify is most proper with this potential function?

Best Regards,

this is the wrong question. your problem is most likely not be solved
by changing the neigh_modify one. at best you'd cure the symptom.

the default value for neigh_modify one is 2000. that means, the
neighborlist code guarantees to reserve space for at least 2000
neighbors. 2000 neighbors is more than sufficient for normal atomic
systems with cutoffs of up to 15 angstrom. eam potentials on the other
hand usually have rather short cutoffs and the average number of
neighbors per atom is frequently less than 100.

thus in order to get the error message about overflowing neighbor
lists typically means one of the following things (with decreasing
probability):
- your initial geometry is wrong (this can be easily verified by
inserting a "run 0" statement. if the error happens there, then this
is your problem).
- your potential or other input file settings are incorrect or bad.
(this is most likely the case, if you get past the previous test).
- you are doing something in your input that pushes the "master
cutoff" for building neighbor lists to a very large value. (then the
cure is to first find out if you really need that, if yes, you should
come back to this list with more details).

if i was a betting man, i would put my money on the second option,
based on what i recall you have posted in the past.
