Droplet Contact Numbers and Probabilities (DCNumPro)
Determine droplet contact numbers and probabilities based on
the median and the standard deviation of a droplet size distribution.
Source code of DCNumPro: https://git.rwth-aachen.de/avt-fvt/public/contact-numbers-and-probabilities/
DCNumPro uses a 3D cell-based Voronoi library based on voro++: https://github.com/wackywendell/tess
