What I do is have a perl script generate a pvd file, which can then be
opened in paraview. The pvd file is a very simple xml file which
basically lists the vtk files. Here is some perl:
#!/usr/bin/perl -w
$DATA = "/path/to/datadir";
$ls = `ls -tr $DATA`;
@files = split(/\n/,$ls);
$i = 0;
open(VELOOUT, ">$DATA/velo.pvd");
print VELOOUT "<?xml version=\"1.0\"?>\n";
print VELOOUT "<VTKFile type=\"Collection\" version=\"0.1\">\n";
print VELOOUT " <Collection>\n";
foreach $file (@files) {
if ($file=~/velo.*.vtk/) {
print VELOOUT " <DataSet timestep=\"$i\" group=\"\" part=\"0
\"\n";
print VELOOUT " file=\"$DATA/$file\" />\n";
$i = $i+1;
}
}
print VELOOUT " </Collection>\n";
print VELOOUT "</VTKFile>\n";

So basically, in the data directory I have a bunch of files representing
the timesteps as velo000000000.vtu, velo000000001.vtu, etc. This file
creates a pvd file from them.

Hi John,<br>
<br>
You mentioned using vtu files; are you sure the same method will work
for the legacy vtk format that Hom is using? I've been under the
impression that Paraview 3 doesn't support timesteps with that format,
and that the xml and legacy formats can't be mixed. I'd be happy to
learn otherwise, though, since I've also been using legacy vtk files
for unstructured grids of FEM data, and could animate them in earlier
Paraview versions. (My plan so far has been to switch to the .vtu
format and then use a pvd file, as you said.)<br>
