<div>Question from a user:</div>
<div> </div>
<div>I would like to use paraview to do the following:</div>
<div> </div>
<div>1) Integrate a nodal variable over a volume (IntegrateVariables filter does this)</div>
<div> </div>
<div>2) Then, integrate the result of the volume integral over time (cumulative integral)</div>
<div> </div>
<div>The "IntegrateVariables" filter works just fine to integrate over the volume, and I can plot the results of it over time by selecting "RowData" from the "PlotSelectionOverTime" filter. I just can't figure out how to do #2 - integrate these results over
time with something like "numpy.trapz" or "scipy.integrate.cumtrapz".</div>
<div> </div>
<div>I feel like this has probably been asked a million times, but I still seem to have trouble with it. I think I usually fall back to other post processing tools. Can this be done all in Paraview?</div>
<div> </div>

<div>Thanks,</div>
