Hi, I have a solution file, resulting from multiprocessor wherein solutions are spread.

The paraview is outputting the following error, when I open ‘pvtu’ file.

```auto
"ERROR: In /opt/glr/paraview/paraview-ci/build/superbuild/paraview/src/VTK/IO/XML/vtkXMLDataReader.cxx, line 410
vtkXMLUnstructuredGridReader (0x7fc457f49a60): Cannot read point data array "f_24" from PointData in piece 0. The data array in the element may be too short."

```

while each of 'vtu’files are being open without any error.

Can anyone guess what is the error with my pvtu file format?

Thanks in advance

Jaekwang Kim.

Hi @jaekwangjk12

Please share your .vtu and .pvtu files.

Best,

The error is quite explanatory, your .pvtu lists some sarrays:

```auto
    <PCellData>
      <PDataArray type="UInt32" Name="connectivity" />
      <PDataArray type="UInt32" Name="offsets" />
      <PDataArray type="UInt8" Name="types" />
    </PCellData>

```

But they are missing from your .vtu files
