Hello gmx-users!
I am trying to make a simulation video in which a water droplet is
rolling or sliding on a surface. Due to a periodic boundary conditions
a droplet is not whole all the time but it disappears from the right
and appears from the left in cycles.
I think that I could create more visual video by removing the lateral
motion of the center of mass of a droplet so that the droplet would
stay whole
in the middle of simulation window and the surface would translate
below the droplet. I am not exactly sure how realistic this kind of
video would be and would like to know if someone has better ideas?
If there are no better ideas I would need advices to be able to create
a such trajectory or video. Right now I am struggling with trjconv
which might be suitable for this purpose. However, if I use the
droplet as a group for translational fit (-fit translation) I get
trajectory in which the whole system wanders strangly (laterally (the
surface moves first to the left and then back to the right) and also
in perpendicular to the surface due to the lowering of the height of
the center of mass of the droplet during the simulation) and the
droplet wont stay whole in the middle of the box. Any ideas what I am
doing wrong or how I would be able to get rid of even this lateral
wandering so that I could at least see how realistic this procedure is?
Thanks for your time and help in advance,
Janne
