Dear All,
I am currently getting an error when I try to open a specific .vtu file with ParaView:
```
ERROR: In /Users/kitware/dashboards/buildbot-slave/a64f5607/build/superbuild/paraview/src/VTK/IO/XMLParser/vtkXMLDataParser.cxx, line 654
vtkXMLDataParser (0x7ff36794ffb0): Error reading uncompressed binary data header. Read 0 of 4 bytes.
ERROR: In /Users/kitware/dashboards/buildbot-slave/a64f5607/build/superbuild/paraview/src/VTK/IO/XML/vtkXMLUnstructuredDataReader.cxx, line 632
vtkXMLUnstructuredGridReader (0x7ff367947f70): Cannot read cell offsets from Cells in piece 0 because the "offsets" array is not long enough.
```
The version of ParaView I am using is 5.8.0 in a macOS 10.15.5 (Catalina). I should add that I usually open similar files created in the exact same way with no issues.
I have attached the file in [this](https://ikpcloud.ikp.physik.tu-darmstadt.de/index.php/s/uyVXZ25vTSeWyFg) link, if anyone would be able to try and/or take a look and shed some light on this issue.
Thank you very much in advance,
Sabrina

Hello Sabrina,
Have you found a solution to your problem by any chance? I am using ParaView 5.9.0 on Windows 10, and I went into the same issue.
Thank you!

Hi Ethan,
Not precisely but the problem went away when I reduced the size of the file (\<2GB).
Hope this helps,
Sabrina

Dear All,
I have the same issue with ParaView 5.10.0-RC2 on Windows 10.
```auto
ERROR: In C:\glr\builds\paraview\paraview-ci\build\superbuild\paraview\src\VTK\IO\XML\vtkXMLUnstructuredDataReader.cxx, line 680

```
Is there any methods to solve this problem?
I will be grateful for any help you can provide.

Hi Freda, I got away with this issue by deleting some of the fields I don’t need. So my .vtu file size was maintained below 2GB, roughly.

Hi Ethan,
Thanks for your advice.
I’ve generate a small testing file. (146.7 KB)
But the problem still exists.

@mnpica you file is most likely malformed. How did you generate it ?

In the third line of the file (Job-netduino-2\_0-10\_0-C3D8-HT\_Step-1\_PART-GLOBALf001.vtu), the number of cells declared seems to be different.
In fact, it can be loaded by modifying as follows:
> NumberOfCells=“208”

I’m trying to convert Abaqus .ODB file into .vtu file via
[https://github.com/Liujie-SYSU/odb2vtk](https://github.com/Liujie-SYSU/odb2vtk)
Is there any other solution for Abaqus file?
Thanks!
