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.

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.
