we search for particular geometry for an open channel such that liquid droplets would move forward and not backward (‘liquid diode’).
we have samples within the range of 10 to100 microns width open channels and a liquid is dropped on them so the capillary forces drive the liquid in them.
we need to calculate the front edge velocity and distance.

Can you help us find a way to automatically track the liquid flow in this complex geometry?
