[Paraview] FW: sum of values at all nodes

[David E DeMarle]

In the mean time, you can do it via Tools->Python Shell and this script:

Start up paraview and apply wavelet source for example. Then open
python shell and do this:


Python 2.5.1 (r251:54863, Jan 13 2009, 10:26:13)
[GCC 4.0.1 (Apple Inc. build 5465)] on darwin
>>> from paraview.simple import *
>>> mm = servermanager.filters.MinMax()
>>> mm.Operation = "SUM"
>>> print pm.GetProxiesInGroup("sources")
{('Wavelet1', '114'): <paraview.servermanager.Wavelet object at 0x2d9c9910>}
>>> wavelet = pm.GetProxy("sources", "Wavelet1")
>>> out = servermanager.Fetch(wavelet, mm)
applying operation
>>> out.GetPointData().GetArray("RTData").GetValue(0)
