[Paraview] Time Source for Data Arrays

[Daniel Frisch]

Hello,

in Biomedical Engineering we often work with large datasets where the
geometry doesn't change over time but the scalar values change. Therefore
we use to save the data as single geometry with many variables (data
arrays) that are named according to the time index.

It would be very convenient if ParaView could recognize these data arrays
as time index again. I am looking for the following filter:

INPUT
- Dataset with
    - one geometry
    - some individual variables (p.ex. material class)
    - and thousands of variables / scalar data arrays with consecutive
names like
         - fwd_calc_0000.000000
         - fwd_calc_0000.001000
         - fwd_calc_0000.002000
         - fwd_calc_0000.003000
- Regular expression that matches the wanted data arrays and extracts the
numeric time value

OUTPUT
- Dataset with
     - geometry
     - the individual variables
     - Time dependence according to the variables that are named fitting
for the regex

The filter itself must be possible: TimeSource creates time index data out
of nothing.
I learned about vtkFileSeriesReader, but I don't want to save each timestep
into a separate VTK file with its own geometry since the geometry stays the
same.
Such a filter would be very useful to many of us and has been awaited for a
long time.
