When using the SMD package, can we apply the periodic BC?
(I do not mean the periodic BC for the z-direction for 2D simulations)
Let me take an existing simple case for example,
In this 2D case, the original setup was to pull a “rubber strip” in the y-direction. But when I want to make the width of the “rubber strip” as if infinitely long, i.e. by setting periodic BC in the x-direction, the result was still the same as non-periodic. In addition, if I modify the case to be the push situation instead of the pull, it did not work out as I expected, as shown in the attached Figures 1, 2, and 3.
Do I have to add anything extra in the input script, or doesn’t SMD support the real periodic BC yet?
I appreciate if you would share any point of view in my question.
