Hello,

By force-free, do you mean a traction-free boundary condition? If so, by default, all boundaries on which no boundary conditions are applied explicitly have traction-free boundary condition applied on them. So you don't need to do anything :) If you check the stress on such boundaries, it may not be exactly zero (since this is a numerical solution, not an exact one), but the stress values should be very small.
