[Paraview] XYZ format in PV

[Moreland, Kenneth]

If you have the same number of points in each time step, you could use the Exodus II format. The documentation is here (https://cubit.sandia.gov/public/documentation/MailingList/cubit/04/att-0110/exodusII.pdf) and you can download the source to the library here (http://sourceforge.net/projects/exodusii/).

So then what is the best format to use while handling time-varying data in ParaView? I currently use .csv files, but there is a separate file for each time step (so might go to about a million files for that many number of time steps).

Thanking you,
Rohit

It looks like the XYZ format could use a little love in ParaView. There are two XYZ readers in ParaView, and they both seem to have problems.

The first reader is labeled a "XYZ Files" and is actually one of the readers of the VisIt bridge. It works OK except that it does not handle time.

The second reader is labeled "XMol Molecule Files". That uses the vtkXYZMolReader class in VTK. The reader as many more features including time support (in a really outdated way), but there appears to be a bug that is causing it to crash all the time: http://www.paraview.org/Bug/view.php?id=14203

Dear all,

I'm trying to import my time varying particle position data from an XYZ file format. In my file, instead of radius of particles, I mention what kind of particle it is (lets say C, H or O).
Now I would like to associate different radii with the different particle symbols. How do I do it in ParaView?

Next, if I have a time varying data, (file attached along), then why is ParaView not able to understand that there are multiple time steps? I am using a standard XYZ file format.

Thanks a lot,
Rohit.
