I'm little confused about setting size of modeling box and number of
particles in it.
boundary p p p
lattice sq 7.5
region box block 0 1000 0 200 -0.005 0.005
As I understand this parameters means, that
lattice spacing is 7.5 Angstroms (unit cell is a cube with size 7.5x7.5x7.5)
box block will be X x Y x Z = (0; 7500)x(0; 1500)x(-0.0375; 0.0375) Angstroms
Is that correct?
And what will be a number of particles?
