[Paraview] Algorithm to find grain neighbors

[Zhang,Ying]

Hi Ken,

I work in Research Computing at University of Florida and have a user (Cc'ed) who is using Paraview to visualize his grain image on our computing systems. 

Steven, could you explain to Ken about your image and the information you are trying to find? 

Thanks,

Ying
