[Paraview] paraview making up numbers

[John Doe]

I tried this and it created a vtm file, a directory, and a file in the
directory.  I could see places where there are a log of "nans" and
1e307's.  Can paraview read nan's and what does it do with them.

  Is there anyway to create a flat file format for a vtm file?

Is the ensight format any easier, or just superior?  Any
recommendations for a format appreciated.

Requirements:
1. Different regions (or pieces) have different data arrays with
completely unrelated names.

Optional (But would be really, really nice):
1. Documented
2. Single file format
3. Different elements in the same region (lines, triangles), and
having completely different data arrays per element type.

Thanks,

Juan
