[Paraview] Decode a vtu file

[Andi Hartarto]

Hello all,

Can I please have guidance/help in decoding a vtu file?

My file is a
<?xml version="1.0"?>
<VTKFile type="UnstructuredGrid" version="0.1" byte_order="LittleEndian"
compressor="vtkZLibDataCompressor">
  <UnstructuredGrid>
    <Piece NumberOfPoints="116"                  NumberOfCells="1052"
         >
      <PointData>
      </PointData>
      <CellData>
        <DataArray type="Int32" Name="TetrahedraRank" format="appended"
RangeMin="1"                    RangeMax="2"                    offset="0"
                  />
        <DataArray type="Int32" Name="TetrahedraNo" format="appended"
RangeMin="0"                    RangeMax="262"
 offset="188"                 />
      </CellData>
      <Points>
        <DataArray type="Float32" Name="Points" NumberOfComponents="3"
format="appended" RangeMin="2003013.3465"         RangeMax="2003224.1668"
      offset="812"                 />
      </Points>
      <Cells>
        <DataArray type="Int64" Name="connectivity" format="appended"
RangeMin=""                     RangeMax=""
offset="1680"                />
        <DataArray type="Int64" Name="offsets" format="appended"
RangeMin=""                     RangeMax=""
offset="5892"                />
        <DataArray type="UInt8" Name="types" format="appended" RangeMin=""
                    RangeMax=""                     offset="8116"
     />
      </Cells>
    </Piece>
  </UnstructuredGrid>
  <AppendedData encoding="base64">
  (data long list)

The file can be found in this link:

I don't understand how to decode a vtk file and couldn't find anything in
google. I've tried using some scripts in python for base64 but it didn't
work..

The reason why I need to decode this is because somehow this vtk file which
load in paraview perfectly becomes a 2d file in another software "MOOSE" ..
So I think somehow in the encoded data is telling the other software "only
display the 2D intersection of blocks". But I want a 3D cube not a 2D
surface. If someone knows about this please tell me .

Thank you,
Andi
