[lammps-users] units and origin

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" ?

thanks

You'll need to read the doc pages for these details.

The origin/orient commands are now part of the lattice command.

The pair_style lj/cut and pair_coeff docs describes how to define
epsilon/sigma.

The Domain too large error is likely happening b/c your simulation
box is not setup correctly.
