I have defines some regions of cells based on thresholds and assigned them regionIDs and also calculated a scalar value (Encaps Vol) for each cell. I would like to sum all the scalar values (Encaps Vol) in each region. I’m struggling as the calculator does not allow boolean operations.
I could set another threshold to isolate each regionID, but I’d like to do this in 1 go. I’d also like to do it in the GUI without python scripting or exporting to excel.
Any help would be appreciated.
Not doable with a calculator.
What you can do is :
- Add a Threshold filter for each region
- Add an Integrate Variables filter on each Threshold
Alternatively, a programmable filter would do the trick in a single step but you would need to write it in python.
Mathieu nailed it.
Yet another option would be the Find Data dialog. Make selections, extract selection, integrate variables filter.
I am also interested in this @mwestphaland and @wascott. If you want to do this with a programmable Filter, what would be the way to locate each of the elements that have a specific region id for a VTK unstructured grid? I need to do even more processing on the results of each of the regions and compare them to each other (looking at histograms of different features of the regions).
