[Paraview] vtu files with two pieces

[Sreejith Kuttanikkad]

Dear all,

I have tried to write an ascii vtu file with two pieces as shown below.
However when I opened it using paraview, i can only see one data set.
Could you please tell me the format of  vtu files with two pieces.  How can
i  get both data sets into paraview.?

<?xml version="1.0" ?>
<VTKFile byte_order="LittleEndian" type="UnstructuredGrid" version="0.1">
<UnstructuredGrid>
<Piece NumberOfCells="4" NumberOfPoints="4">
<Points>
<DataArray NumberOfComponents="3" format="ascii" type="Float32">
0 0 0 1 0 0 0 1 0  1 1 0
</DataArray>
</Points>
<Cells>
<DataArray Name="connectivity" format="ascii" type="Int32">
