v5.10-RC1 SPH Interpolator GUI needs rework
as discussed in https://discourse.paraview.org/t/sphvolumeinterpolator-with-cutoff-array/3119, the GUI panel for Array Selections lets the user select a Cut-off Array from a list of PointData arrays available in the source point cloud. This is wrong, since the Cutt-off array should be taken from the input point data. As such, the definition of the probes (Line, Plane, volume) does not enable the definition of a Cutt-off array.
An alternative would be to use the SPHDatasetInterpolator, with an added probe (e.g Plane) defined elsewhere, with its own Cutoff array. This does not work either, the GUI marks the array as "Cutoff (?)". pvbatch also fails. Here is an attached Python script to demonstrate the use of an SPHPlaneInterpolator vs. an SPHDatasetInterpolator. pvSimpleTestSPHInterpolator.v510.py
