[Paraview] Fwd: Visualization in ParaView/VisIt

[David E DeMarle]

You should probably write an XDMF file (
http://www.xdmf.org/index.php/Main_Page) that describes the hdf5 file. Like
a "text" file or a "binary" file, "hdf5" files can contain anything, so the
XDMF file adds a bit of helpful context.

Here is a sample xdmf file that reads in three arrays from a named hdf5
file that define the cell connectivity. coordinates, and one scalar field.
The data in this case looks like a rubix cube of 27 hexes.

<Xdmf xmlns:xi="http://www.w3.org/2003/XInclude" Version="2.2">
  <Domain>
    <Grid GridType="Uniform">
      <Topology TopologyType="Hexahedron" Dimensions="27">
        <DataItem Dimensions="27 8" NumberType="Int" Precision="8"
Format="HDF">/Users/demarle/Desktop/rubix.h5:/Data0</DataItem>
      </Topology>
      <Geometry GeometryType="XYZ">
        <DataItem Dimensions="64 3" NumberType="Float" Precision="4"
Format="HDF">/Users/demarle/Desktop/rubix.h5:/Data1</DataItem>
      </Geometry>
      <Attribute Name="RTData" Active="1" AttributeType="Scalar"
Center="Node">
        <DataItem Dimensions="64" NumberType="Float" Precision="4"
Format="HDF">/Users/demarle/Desktop/rubix.h5:/Data2</DataItem>
      </Attribute>
    </Grid>
  </Domain>
</Xdmf>
