Neighbor list overflow!!

Hii…

I am trying to run a simple simulation with one box filled with small particles with volume 30301 and then I will apply strain and calculate stress. But before that while trying to run the simple box simulation I found the following error,

Neighbor list overflow, boost neigh_modify one (…/neigh_half_bin.cpp:415)

I have read several previous discussions and from there I changed my neigh_modify command as following

neigh_modify delay 0 every 1 check yes page 100000 one 4000

then the error goes away but the simulation hangs after the first step.
I also found this might be because of “bad potential parameter”

I use the following potential…

pair_style soft 1.12
pair_coeff * * 1.0

Can anyone help me figure out what I should do to solve this problem !!!? i am attaching my input file for your kind consideration ! Thanks in Advance. :slight_smile:

​i don't think it "hangs", it is probably just very, very slow.​

I also found this might be because of "bad potential parameter"

​no, but look at this:

lattice sq 85.0

​density of 85? seriously?​​

​with a very short cutoff of 1.12 sigma and a 2-dimensional system, you
should *never* reach the point where you have more than 2000 neighbors per
atom (the default setting for neigh_modify one) for any reasonable system.

GI-GO!

Thank your Dr. Axel. I didn’t notice the typo. Now the file is running well. :slight_smile:
