/* ERROR/WARNING messages:

E: LRT otion for Intel package disabled at compile time

This option cannot be used with the Intel package because LAMMPS was not built
with support for it.

W: No fixes defined, atoms won't move

If you are not using a fix like nve, nvt, npt then atom velocities and
coordinates will not be updated during timestepping.
