[Paraview] Integrate Variables divide cell data by volume has no effect?

[Shuhao Wu]

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?

Thanks,
Shuhao
