Re: [lammps-users] regarding combining of two fix command in one fix command

This is a bit of a tricky one.

You would have to either modify the fix move source code to have an option (e.g. screw) that implements such a “screwing” motion by combining the rotation with a linear displacement in the direction of the rotation axis, or you’d have to implement the entire motion with variables, which could be a bit complex but not impossible.
