Marker for Bubbles, any Idea how to implement?
 

Hi,
I m working on the implementation of bubble-bubble interaction model with disjoining pressure under compressibleInterFoam.

1. the first problem is how to implement a marker for distinguishing between different bubbles (I have more than 3).
2. the second is how to comput the distances between bubbles interfaces.

It will be greet if some one could give any hint, idea or pseudo code.
Many thanks
Jaming
