[Paraview] CxxOverlappingAMRExample with Catalyst Live

[Jim.Eliot at awe.co.uk]

Good afternoon,

I have been trying to use Catalyst Live with the CxxOverlappingAMRExample from the ParaView Catalyst Example Code repository [1] but I see an error when I try to visualise the data from a ParaView client. The client connects to the simulation successfully and PVTrivialProducer1 appears in the Pipeline Browser. The Information tab shows it as an Overlapping AMR Dataset with 3 levels. However, when I click on the PVTrivialProducer1 icon, ParaView prints an error then segfaults. The error is something like:

    Warning: In <src-dir>/VTK/Parallel/Core/vtkCommunicator.cxx, line 394
    vtkSocketCommunicator (...): Cannot receive vtkOverlappingAMR

I have tried this with both ParaView 4.4.0 and 5.0.0 with the same results. The example works fine when I am using non-Live Catalyst (i.e. it writes out a bunch of vtm files that I can read into ParaView).

So I am wondering, are AMR meshes not supported by Catalyst Live? Do I have to handle AMR meshes differently when using Catalyst interactively?

Many thanks,
Jim
