[vtkusers] Separation of <Points> and <Cells> datablocks from Unstructured Grid (.vtu) files

[Frank Everdij]

Replying to my own post:

As for the monolithic approach in a single .vtu file i've found a 
paraview-developers post by Mathieu Malaterre in 2005:

http://public.kitware.com/pipermail/paraview-developers/2005-June/000239.html

I've tested it in Paraview 3.14.1 and even though this is relevant to 
Paraview 2.2 beta, this approach still works fine: a single <Points> and 
<Cells> block followed by multiple <PointData> or <CellData> blocks with 
TimeStep attribute in the <DataArray> blocks. If you don't specify a 
TimeStep attribute then the <DataArray> block is valid for every 
timevalue. Additionally you need:

<UnstructuredGrid TimeValues="1 2 3">


Still, i would like to know if this will work with newer versions of the 
VTK toolkit, or that we have to change this in the future. I for myself 
would like to prefer creating new smaller files with separate <Points> 
or <Cells> data when adding progressive simulation data over handling a 
single file.
