[vtkusers] how to avoid overlapping (ghost) layer in *.pvti files

[Kaya Onur Dag]

I have my own cfd solver in which I was using *.vti for paraview input but
decided to use parallel data write with *.pvti format and do node
parallelisation.

My *.pvti file is like :

<?xml version="1.0"?>
<VTKFile type="PImageData" version="1.0" byte_order="LittleEndian"
header_type="UInt64">
  <PImageData WholeExtent=[/QUOTE][/QUOTE]"       0      31       0      31
      0      31" Origin="  0.000000000000E+00  0.000000000000E+00
 0.000000000000E+00" Spacing="  0.196349540849E+00  0.196349540849E+00
 0.645161290323E-01" GhostLevel="0">
      <PPointData Scalars="u v w">
    <PDataArray type="Float64" Name="u" NumberOfComponents="1"
format="appended"/>
<PDataArray type="Float64" Name="v" NumberOfComponents="1"
format="appended"/>
<PDataArray type="Float64" Name="w" NumberOfComponents="1"
format="appended"/>
</PPointData>
<Piece Extent="0 31 0 31 0 15" Source="data0_0.vti"/>
<Piece Extent="0 31 0 31 16 31" Source="data0_1.vti"/>
</PImageData></VTKFile>


The problem I am facing is I am having a gap in between z-axis 15-16 -
which paraview complains.

I know that the solution is to have a ghost (overlapping) layer (can't
understand why since I am using point data?), and the issue is that my code
is not capable of generating overlapping nodes, unless I code it up and
manually transfer ghost layers at each data output stage for the sake of
being able to write data in parallel but it feels like an overkill...

Any suggestions?

Thanks in advance.
