[Paraview] time series with Xdmf-Files

[Natalie Happenhofer]

Hi!

This might be a stupid question.. but I have now such a .xmf file with the temporal collection, but how do I play it? I load it into paraview, and then I press the "play" button above, but I can´t see anything moving..

thx,
NH

Hello Natalie,
I don't know if this will be helpful (since you already have all of those XMF files), but the standard way of doing the time animation with Xdmf and ParaView is to have all of the time steps in one XMF file as a "temporal collection". Each time step in the file could refer to a separate HDF5 file for its data. There are ways of enabling animation for a series of files using a time-unaware reader in ParaView, but I think it would be easier to write a script to combine all of your XMF files together into the time-aware format that is supported by Xdmf.
I'll put an example below.-Eric

I have a lot of Xdmf - Files which I would like to animate as a video in paraview. For every Time Step I have a separate .xmf -File and a corresponding .h5 file. Does anyone know how to do that?

thx a lot,
