Thank you for your suggestions! Still: No matter which one I choose, I
would have to edit every new set of files, before I can load it into
ParaView.
I have now set up a (very small) pvypthon module vtuseries.py, which
looks like this:
import os,glob
import paraview.simple as pv
def load(directory):
"""Load VTU file series from given directory
"""
pattern = os.path.join(directory, '*.vtu')
files = glob.glob(pattern)
reader = pv.XMLUnstructuredGridReader( FileName=files )
Putting this module on the path of the ParaView Python Shell gives me
the opportunity to run
import vtuseries
vtuseries.load(directory)
from the Python Shell, which creates a reader with all the vtu files in
the given directory. Maybe this is not even easier than the other
suggestions, but it is closer to what I had been looking for originally.
I thought there might be a better way to run python code depending on a
given parameter (the input directory) in the ParaView GUI, but I have
not found it.
One last question to the developers: Is there a special reason, that it
is not possible to select several VTK files from the Open dialog, which
are then opened as a sequence?
Kind regards
Ian

Well, if you don't want to rename the data files then you could use
a PVD wrapper file:

Never created one myself, but you could write out one from paraview
and modify it.
But maybe somebody else has a better idea altogether...

What about creating symbolic links (or shortcuts) to the
real files. In this way you preserve the original filenames.
PVD wrapper files also worked fine for me in the past.
I have not used them recently however.
