Hello,
I need to extract a subset volume from my domain in order to make same calculation on the data. How can I do this? I need this subset at each time step.
Attached a figure showing the domain, I need to extract the second volume from the left, the light bluish.
Thank you,
Valentina

The correct solution may depend on how you define ‘subset’. If it is defined by some specific values of attached data, you can look at:
- Threshold filter
- Clip filter with ClipType = Scalar
- Edit menu / FindData to create a selection (points or cells) and extract this selection
If it is a pure geometric definition, it can be harder

Maybe you can consider the IsoVolume filter as well.
It’s essentially a two-sided Clip (by scalar) I believe.
