[lammps-users] delete_atoms porosity cube 0.5 10

By using the above command, I can make cube region lose 50% atoms.
However, if I want to have big pores in cube region, can I use a large “random number seed” to do that?
Otherwise, how can I do it?


If you're asking how to delete atoms in some inhomogenous
manner within a volume,then the delete atoms command
can't do that. Not sure how you would hope to specify
conditions for that in a general manner.

I think you're better off pre-processing a data file to remove
exactly what you want, before you input it into LAMMPS.


I will note that if by "big pores" you mean
a few spheres, then you could always use
the delete atoms command multiple times
with different sphere regions.
