Thank you. Is it possible that this is caused by the trapped molecules inside my
tube? My tube ends are on the box edges so water cannot migrate outside the tube
where are the other water molecules.
I take it that your tube is finite, not infinite? I guess I'm confused at this
point - there are water molecules inside the tube? I thought the whole point
was to not have water inside.
In any case, if your tube is finite with the ends at the box edges, you likely
have clashes between tube atoms that cause the water to start kicking around.
If you have a small number of molecules within the tube, then yes, they can
become unstable in isolation. This commonly occurs with voids in simulation boxes.
