[Paraview] Saving integrated data on an animated slice

[Adriano Gagliardi]

Richard,

I don't thionk you'll need the first programmable filter. The following
should be a start:

vtkUnsData = self.GetInputDataObject(0,0)
fout = open(filename,'a')
#then you can use the write function to write data to file ie
fout.write("%s" % (vtkUnsData.GetPointData().GetTuple1(0))
fout.close()

I've never used Surface Flow so don't know what type of data-set you will be
working with.

Good luck!

Adriano

Thanks, Adriano.

This seems to be a very good idea. I could attach a Programmable Filter
script after my "Surface flow" filter.
My script should first create the data file with an "append" status so that
it would not be overwritten at each animation step, then it should output
the "Surface Flow" point value at each step. So maybe two Programmable
Filter scripts? The first one before the animated Clip filter to create the
output file, the second after the Surface flow filter. Maybe a pipeline like
that:

- Programmable Filter 1 : Creates the output file with "append" status. 
Should execute once!
- Animated Clip : X coordinate of the cutting plane origin is animated.
- Surface Flow filter: performs integrations and gives a "Surface Flow" 
point value.
- Programmable Filter 2: write the "Surface Flow" value. Should execute at
each animation step.

I will try to do that, but I am not very easy with Python, so if someone can
help me to write these two scripts, thanks in advance.

Richard.
