<p>The IntegrateVariables filter creates a spreadsheet of PointData (or CellData, depending on where your data is stored in the filter just before IntegrateVariables) with the integral of your data over the volume/area/length depending on if it is 3D/2D/1D
data respectively. <br>
</p>
<p><br>
</p>
<p>It also adds a field to the CellData array that will be Volume/Area/Length respectively.</p>
<p><br>
</p>
<p>My guess is if you aren't seeing it immediately it is because you are looking at the PointData array and not the CellData array. In the SpreadSheetView that opens up, change the Attribute dropdown from Point Data to Cell Data.<br>
</p>
<br>
<p>Also, as a note -- the values for your variables (pressure, velocity, whatever) are multiplied by the length scale, so if you want the average value in the domain, you need to divide it by the length scale.</p>

<p><span style="font-family:"Calibri",sans-serif; color:black">Your best bet would be to use the Threshold filter to extract the region where the scalar is greater (or less than) 0.5 and then use the IntegrateVariables filter on the Threshold.
