[Paraview] paraview & HDF5/XDMF: how to control memory usage?

[Favre Jean]

Allow me to add my 2 cents to this thread, since Dave talks about a new generation xdmf reader/writer in the making.

I too use a series of files for each timestep ( one XMF file and one HDF5 file per step), since I have discovered that creating temporal collections does not work correctly if the grid resolution changes over the timesteps. I have a multi-resolution simulation. The grid starts at low res., then the resolution steadily increases. Using a temporal collection in XDMF, the grid resolution of the first grid in the temporal collection is used throughout the full time series. I see my data is read correctly, but is truncated by the lowest resolution bounds.

I hope this gets fixed with the new reader.
TIA.
