How to output a series of cells for paraFoam view
 

Now I can acquire a List, which include all labels of cells I need. How I can output this List to some directory, e.g. constant/polyMesh/set, for paraFoam to observe these cells directly?

I'm eager for any valuable suggestion.

i think, you can use utility c
 

i think, you can use utility cellSet for generating list of cells and utility foamToVTK with switch -cellSet, then you can run paraFoam (or paraview)

f.e.:

1) cellSet . case-1
2) foamtToVTK . case-1 -cellSet <setgeneratedonstep1>
3) paraFoam . case-1
