Thanks for the reply!
I have tried this setup, however I could not find a filter that would
produce the correct output with the CreateWriter. When using the
PlotVariablesOverTime it does not work, as it produces a
vtkMultiBlockDataset as opposed to a vtkTable that is required by the CSV
writer.
The solution I have found was to use a programmable filter in a similar
setup (with the appropriate selection of the block and column indices):
progFilter=ProgrammableFilter()
progFilter.OutputDataSetType='vtkTable'
progFilter.PythonPath = ''
progFilter.RequestInformationScript = ''
#progFilter.RequestUpdateExtentScript= ''
progFilter.Script = "\
dataTable=self.GetInput().GetBlock(0).GetColumn(0)\n\
output=self.GetTableOutput()\n\
output.AddColumn(dataTable)\n\
"
I believe it is worth mentioning that it is possible to put the debugger
breakpoints (pdb.set_trace()) in the progFilter.Script string and this way
to figure out what exactly the input of the filter is like.
