I have DEM (or LPT) simulation data as point data. I also have the underlying fluid data in field. I want to get values from the fluid where the particles resides (point locations). I would like to use the **ProgrammableFilter** but not sure how to do it.
To be more specific, I have `shearStress` field data (tensor) and I want to get the values of magnitude of `shearStress` at the positions of the particles (point data). I followed the example of subtracting two datasets as mentioned [here](https://www.paraview.org/Wiki/Python_calculator_and_programmable_filter#Programmable_Filter), but it is returning weird results (lots of column values in a single row).

Just use RessampleWithDataset

Oh, how can I be so stupid! I knew this but used it the opposite way earlier 🙄
The correct way to apply in this case is: `RessampleWithDataset > Source data Arrays: cellData; Destination Mesh: pointData` with the options `Pass Field Arrays` & `Pass Point Arrays` enabled.
