bin size

Submitted by Weijing on Tue, 03/28/2017 - 04:28

Hi everyone,

I have a question about number of bins and bin size when using neighbor bin command.
I have read some post regarding to Too many neighbor bins, and it seems that LIGGGHTS limit the number of bins to 200. I tried to figure out how to estimate the number of bins.

number of bins = half size of simulation domain(in xyz direction)/bin size, is this correct?

the optimal bin size is 2*max radius or 4*max radius?
because I find tow posts discussing this setting.

Thanks
