Dear all,
I have just started some simple simulations of arrested structures of
LJ particles at low temperature.
Now I want to analyze their elastic behaviour, and to do so I tried to
apply a shear strain to them.
As I understood fix_deform applies a affine map to the coordinates of
the particles, but isn't this sort of unrealistic in some situations
(i.e. those where the deformation is non-affine in character)?
Is fix_nvt_sllod or some kind of energy minimization after the
deformation the way to obtain the correct non-affine configurations?
Should Lees-Edwards boundary conditions be used instead and are these
already implemented in LAMMPS?
I don't have much experience with these kind of simulations so I
apologize if these questions are naive... are you aware of literature
that would be useful to help me understand the right ways to handle
atomic simulations of sheared systems?
Thanks a lot!
