[vtkusers] VTS File Format

[Gerrick Bivins]

Patrick,
See this post for the basics:
http://public.kitware.com/pipermail/paraview-developers/2005-June/000239.html

I haven't tried it with structured data but it worked for me or  unstructured.
I thought there was a test I referenced that had an example of how to setup the writer, but I could only find this
feature request that has sample code attached. It tests writing out a time series file:

Hope that helps,
Gerrick

Dear all,

My task sounds pretty simple, but I am struggling to find a suitable solution.

We have a flow solver and want to write out various time dependent variables on a structured grid. We choose the VTS XML file format as we are using paraview to visualize our data and further the VTK file formats seem to provide loads of freedom.
The only proper documentation I could find was the 19pages PDF `File Formats for VTK version 4.2'. This one tells me already loads of things, but I am lagging some information to finish writer:

1. If i have 3 dimensional data (x,y,z) , how do I order the data in the StructuredGrid format? Will it be loop over z ( loop over y ( loop over x ( write point ) ) ) or the other way around?
2. Our grid is not changing in time. How can I write a time series with a steady grid in one VTS file? Or is it possible to write a separate grid file, so that I do not have to dump the grid with every time step?

If you could provide a link to a decent documentation about VTK file formats, I would be very please. Searching via Google was very demoralizing.

Thanks already in advance!

Best regards,
Patrick
