<p>Hi David,<br>
I posted a similar query last week: ie how to use vt* xml files to hold data (efficiently) with constant geometry and varying data values. <br>
Please keep me posted if you get any leads on this. <br>
Should this question be posted to the Paraview mail list, which I am not (yet) a member of?<br>
<br>
Found these from a quick search on Paraview list, <br>

<br>
I think the easiest way would be to either write a separate vtp file for each iteration (and then write a pvd file to treat them as a time series for animating in ParaView), or else change your data file format.<br>
<br>
I've never used it, but evidently the Ensight Gold format allows separate files for the mesh and the data associated with it. For my work I use XDMF (</font><a href="http://xdmf.org/" target="_blank"><u><font size="4" color="#0000FF">http://xdmf.org</font></u></a><font size="4">), which would allow you to write one copy of the geometry and the scalars for each iteration to a single HDF5 file, and then the XMF file that goes with it would describe a time series which points to the one copy of the geometry on each "time" step along with the new cluster array scalars.<br>
<br>
Otherwise, as a long-shot, there was some talk on the ParaView mailing list last year saying that vtu files could actually hold multiple time steps, and that someone had patches which would allow pvd files to be read in using "shared" geometry, but I'm not sure what the status of that is...<br>

I already have 10,000 (ok, maybe I'm exaggerating a little bit :) ) file formats to convert from/to, so it'd be nice to keep everything in vt*. Does anyone know what happened to the patches Eric is talking about (either multiple timesteps in a vtu or "shared" geometry?) That thread seemed to die with no resolution.<br>
<br>
Thanks,<br>
