Hello,

I think vtkTemporalDataSet was not meant to be used directly. It does
group data sets together that collectively define a temporally varying
entity, but it is currently only used deep inside VTK and paraview (to
aggregate results together from non time aware producers to satifsy
input requests from time aware filters).

Instead of trying to use that, simply produce a series of .vtk files
from your polydata. Make sure to name them sequentially,
myresult_t0.vtk, myresult_t1.vtk etc. Paraview will then recognize the
set of them as temporally varying.
