[Paraview] vtk collection

[Zenker, Dr. Matthias]

Hi,

I want to write a VTK xml file for a time collection. So far, I have used the following syntax, as found in this document:


<VTKFile type="Collection" version="0.1" byte_order="LittleEndian"><Collection>
 <DataSet timestep="   0.200E+00" group="" part="0" file="./step_1.vtu"/>
 <DataSet timestep="   0.400E+00" group="" part="0" file="./step_2.vtu"/>
  </Collection></VTKFile>

This works well for binary vtu files. Now I want to use ASCII vtr files. With the syntax shown above, Paraview (3.12.0-RC2) throws me the following errors:

snap -------------------------------------------

Opening the vtr files directly works without problems (except that ParaView doesn't seem to recognize the extension .vtr by itself, I have to manually specify "Legacy vtk" as input format).

Questions:

1.      What do I have to change in the pvd file syntax?
2.      Is there a vtk syntax reference where I can learn more about the vtk collections?

Thank you,

Matthias
