Useful Info on LAMMPS:
Professor.....among the last four column 1st one is the z coordinate value. In our case it is a 2d simulation so this value is always zero.
Professor.....among the last four column 1st one is the z coordinate value. In our case it is a 2d simulation so this value is always zero.
The last three values are as following.......
"The
final 3 nx,ny,nz values on a line of the Atoms entry are optional.
LAMMPS only reads them if the "true flag" command is specified in the
input command script. Otherwise they are initialized to 0 by LAMMPS.
Their meaning, for each dimension, is that "n" box-lengths are added to
xyz to get the atom's "true" un-remapped position. This can be useful in
pre- or post-processing to enable the unwrapping of long-chained
molecules which wind thru the periodic box one or more times. The value
of "n" can be positive, negative, or zero. For 2-d simulations specify
nz as 0"
This is what true flag command says.....
"read atom positions and dump atom positions in one of 2 formats
- flag = 0 -> read/dump only atom positions (remapped to periodic box)
- flag = 1 -> dump atom positions plus integer box counts
- flag = 2 -> read atom positions plus integer box counts
- flag = 3 -> read/dump atom positions plus integer box counts
for each dimension, box count of "n" means add that many box lengths
to get "true" un-remapped position, "n" can be positive, negative, or zero
Default = 0"
