Hi All,
I'm trying to visualize some vector component field time series written by a
seismic wave propagation code, and converted into .vtu files by a set of
upstream scripts.
I'm trying to compute the norm of the vector at each timeslice and then
visualize the resulting scalar field. The data

I thought one needs to convert a vtkarray to a numpy array with
x = numpy.array(inputs[0].PointData['Scalars_'])
before doing anything with it.

Hi Frank,
I didn't have a problem with the following on my windows machine using the
ParaView 3.14.1 installer.

try: paraview.simple
except: from paraview.simple import *
paraview.simple._DisableFirstRenderCameraReset()
Wavelet1 = Wavelet()
RenderView1 = GetRenderView()

I am just starting to read this thread so I wanted to answer various
questions here separately.
Your assumption is correct. m = x*x will be 100% evaluated by NumPy. In
theory, this should be pretty much instantaneous for ~1M elements, even for
20 timeslices.
