Interpolate onto part of the domain

Hi there,

This should be simple, but I don’t know what to do.

My input file is a 3D unstructured vtu. Since I am only interested in part of the domain, I want to interpolate data on a structured mesh for that specific part. I would assume the box source + resample with dataset filter can do the trick, but later I figured out the box source can only do the interpolation on the surface… What kind of source should I use for this?


I later found another filter ExtractCellsByRegion, which is a useful way to select part of the domain.

Also, the PointVolumeInterpolator might be what I need. There are options of origins and scale, but they are hard to interpret at first…

And later I found that actually clip is the easiest way to do this. Needs to be more familiar with Paraview.
