[Paraview] XDMF and HDF5 : data corruption ?

[Biddiscombe, John A.]

Tell it that the geometry is XYZ like so ....

<Geometry Type="XYZ">

for example

  <Topology Type="Polyvertex" NumberOfElements="20000 ">
  </Topology>
  <Geometry Type="XYZ">
     <DataItem Dimensions="20000 3" NumberType="Float" Precision="4" Format="HDF">
	  test.h5:/PartType2/Coordinates</DataItem>
  </Geometry>

Subject: [Paraview] XDMF and HDF5 : data corruption ?

Hi,

     I am trying to read the content of an HDF5 file via XDMF with 
Paraview 3.8.1 on OS X 10.5 (PPC), but I get either very large or very 
small numbers being read into Paraview, it seems the data are just 
uninitialized memory.

     Any advice ?

XDMF file
-----------------------------
<?xml version="1.0" ?>
<!DOCTYPE Xdmf SYSTEM "Xdmf.dtd" []>
<Xdmf xmlns:xi="http://www.w3.org/2001/XInclude" Version="2.0">
<Domain>
<Grid>
<Topology TopologyType="Polyvertex" Dimensions="4"/>
<Geometry>
<DataItem Dimensions="4 3"
           Format="HDF">
       xdmf_datasets.h5:/MyDataSet
</DataItem>
</Geometry>
</Grid>
</Domain>
</Xdmf>
-----------------------------


H5Dump
-----------------------------
HDF5 "xdmf_datasets.h5" {
GROUP "/" {
    DATASET "MyDataSet" {
       DATATYPE  H5T_IEEE_F32BE
       DATASPACE  SIMPLE { ( 4, 3 ) / ( 4, 3 ) }
       DATA {
       (0,0): 0.447571, -0.444658, 0.229639,
       (1,0): -0.0218087, 0.27028, 0.57983,
       (2,0): -0.301279, 0.0260453, 0.238798,
       (3,0): -0.376086, 0.430129, 0.464753
       }
    }
}
}
