hello ，three questions.
1. when i use metal for units and fcc for lattice and LJ/Cut for
pair_style , is it right? and how i assign the coefficients for
pair_coeff, i want to know how to match the epsilon and sigma ,which
is the first or the second?
2. and i confused whether and why the command origin and orient have
be deleted in new version?
3. and what mean this error "domain too large for neigh bin" ?
