[vtkusers] VTS File Format

[Patrick Bechlars]

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
