Re: [Paraview] Integrate Variables divide cell data by volume has no effect?
I suspected so as well but didn't know how to convert the point data to cell data until now. So does that mean integrate variables with point data will not be integration weighted by the area?

The DivideCellDataByVolume only operates on cell data and you're integrating a point data array so it won't work the way you're expecting it to. You can use the point data to cell data filter and then try using the integrate variable filter to see if that gives the result that you want.

[Paraview] Integrate Variables divide cell data by volume has no effect?
Hello all, I've been using the filter IntegrateVariables with the option DivideCellDataByVolume = on on a 2D surface. I've noticed that turning this option on and off has no effect on the PointData of the output. No additional cell data is produced either. I thought the idea of the the integrate variables filter is (for 2D): it sums up the values at each point and multiplied by the area associated with that point (*). If the DivideCellDataByVolume option is on, it will divide the final result by the total area. If this is the case, why does the option do nothing, shouldn't the point data be scaled by a constant factor that's the area? (*) how does it associate the points with their areas?
