ParaView volume integral
Hello!
Does somebody knows how to calculate volume integral result in ParaView? I have a unstructured mesh with scale energy source. I would like to calculate the integral energy over the whole mesh. Thanks in advance! 
Greetings yiphome,
I think what you're looking for is the filter "Integrate Variables": http://cmake.org/Wiki/ParaView/Users...rate_Variables Best regards, Bruno 
Thanks
THanks for your help :)

Hi,
I have the same problem. The "Integrate Variables" filter in Paraview is apparently rather disfunctional: it only works for lines and surfaces. Its failure on volumes can be easily demonstrated by integrating over a 1x1x1 cube. However, the underyling VTK library does support volume integration, so it could be just a matter of invoking the VTK function through the Paraview Python interface. Any Paraview nerds that can help out with this? I already tried the Paraviewusers mailing list, but got no response. Cheers! 
I am sorry to disagree but ParaView is able to integrate variables on lines, surfaces and volumes. To verify, try:
Sources > Wavelet (creates a 20x20x20 grid) Filters > Integrate variables This will result in a volume of 8000 as well as RTData integrated over the volume.
