[Paraview] Time Source for Data Arrays

[Christopher Neal]

Hi Daniel,

The datasets that you describe are what most computational physics datasets
are like. The geometry remains fixed while the scalars on the geometry
change with time. The Ensight Gold format is one that I use often. It has
very nice support for time series data where there is just one geometry
file with a set of changing scalars on the geometry.

I'm not sure exactly what you are asking for in your original question. Do
you want the Kitware guys to write a filter that can read some sort of
simulation data formatted in a specific way into Paraview? They would need
more information about the format that you are using i.e. how is the data
structured, etc.

Hope this helps,
