Hi all, This is sort of my attempt to definitively conclude that what I want to do is not possible with the pull code.
For simplicity, here's what I have: a box containing a fully periodic near-linear ssdna chain along Z. I want to enable non-stop translocation in that direction, at a constant rate. The only way I was able to make this type of translocation work is with the constant-force option. However, due to the peculiarities of the system, constant force pulling (physically, in my opinion) makes the motion somewhat jerky, as opposed to constant rate. At this point, I have tried every possible option I could find in the manual (related to the problem), and I just can't make it work. The most I get is a pretty energetic and fun-looking oscillation of the chain along Z. Do you think constant force is my only option? If someone wants to try it out, I can [privately] provide a tarball with the input. Any thoughts?
