Dynamical mechanical spectroscopy

I am trying to apply a sinusoidal strain, Like real DMS
using fix deform command " style wiggle ", amplitude of oscillation is in distance units is there a way to convert it in % pourcentage ? thanks in advance

You could use an equal style variable to compute the value in distance units from a percentage.

Hi thanks for your reply, i am new in lammps is there a way to declare a uniteless variable i am using metal units not lj

Variables have no units.
