[Paraview] Specific OpenFOAM case crashes the server

[Mark Olesen]

Hi Robert,

This sounds intriguing - I wonder if there is something with 32/64-bits involved?

The reader needs a cleanup (https://gitlab.kitware.com/vtk/vtk/issues/17096), but I'm rather short of personal free time to tackle it (and no funding for it at the moment).

However, even after a cleanup the reader will continue to remain rather fragile with regard to handling various dictionary items, especially things like "#includeEtc" that imply a much deeper knowledge of the OpenFOAM logic than is possible based on the output files alone.  It is for this reason that the "skip zero" switch was added. The intention is to skip over the "0/" fields that contain most of the includes. Subsequent output fields will not normally contain any #include directives.  The only slightly odd output element can be "#{" .. "#}" verbatim strings (associated with user-coding), but the reader should silently skip over these and not cause any problem.

Cheers,
/mark

Subject: [Paraview] Specific OpenFOAM case crashes the server

Dear All,

I have been recently testing remote rendering in paraview and I seem to have
concocted a case which breaks remotely works locally. The case is an OpenFOAM
U-bend simulation and I am happy to share the files. They're about 61MB.

On the remote side I get:

pvserver: /.../viz/ParaView-v5.4.1/VTK/IO/Geometry/vtkOpenFOAMReader.cxx:3798: void vtkFoamEntryValue::ReadList(vtkFoamIOobject&): Assertion `"Label type not set!" && this->GetLabelType() != NO_LABEL_TYPE' failed.

On the local side it looks that I simply get disconnected which makes sense
seeing that the server core dumped.

I tried to remove all weirdness from this case and at the moment it is really
just a tet+quad mesh and some case files. If I open the case directly with the
client everything works.

I am really keen to solve it as when remote viz works, it's absolutely
brilliant. I would appreciate comments. Thanks.


A side note is that looks to me that PV OpenFOAM reader cannot handle
"included" files used by OpenFOAM.

Best wishes,
Robert
