XDMF reader failing to load matrix attribute

ParaView Support
1

I am using ParaView 6.2 and now matrix attributes are failing to load properly. I have a 2D array of data in an HDF5 file of size 10000 x 3. It’s defined in my XDMF file as follows.

<Attribute AttributeType="Matrix" Center="Node" Name="Attribute1">
        <DataItem Dimensions="10000 3" DataType="Float" Precision="8" Format="HDF">
          file.h5:/GroupName/Attribute1
        </DataItem>
</Attribute>

When I load the file and try to view the data array, ParaView freezes and the console outputs the following continuously for each row

[paraview ] vtkTable.cxx:429 ERR| vtkTable (0x223a5220): Column "Attribute1_0" must have 10000 rows, but has 1.

I’ve verified the format in my HDF5 file and it is in fact a 2D array of 64-bit floats with 3 columns. I am using the standard XDMFreader. Loading Scalar attributes works fine.

Thanks,
Sam
