Thanks Amy.
My problem is that I need to output the values on all of the regions on
the outside of my 3D mesh and would like to use polyData for that. Guess
I'll have to create a subdirectory for every region and create one file
per time in there. This would allow me to look at time evolution on a
region.
Is there no file format/reader which has something of the like (regions,
named boundaries)?
Thanks,
Mattijs
