Hi, all,
As described in the LAMMPS manual, command ’ fix_addforce ’ could add fx, fy, fz to the corresponding component of force of each atom in the group, however, does this mean a constant increment will be added for every time step? For example, if command ’ fix kick flow addforce 1.0 0.0 0.0’ was used and for a 1000 timesteps running, will the final fx of the atoms in the group be 1000(suppose fx at the start is 0)?
By the way, there are many examples of deforming a nanowire(with free surface along the axial direction) through displacement control, are there some ways to deform such nanowire by load control?
Thanks.
