funkySetFields and multiple sets and fields
This is an attempt to get a simplified version of what I outlined in the the thread located here, as I want to "fix" fields that have been mapped with inconsistent boundaries.
I'm using funkySetFields to create an initial field (mass fraction will be my example), with value -1, and then mapping data from an old mesh on top of that. Wherever the new mesh exists where the old one didn't, the mass fraction should be -1.
Now for each negative valued cell I want to find the nearest cell that does not have a negative value and copy its value over to the new one. Since the deviations in geometry are small (mainly due to remeshing using snappy with a different resolution). I'd like to do this in funkySetFields for now, but am stuck on how I would be able to check the distance between cells. Maybe I should just make my own utility?
