[Paraview] Interfacing with FE simulation using Catalyst

[Andy Bauer]

Hi Alexandre,

If you could reproduce the errors that you're getting in one of the
examples, we could try to track that down. I tried using your script and
didn't have any issues with the CxxFullExample in the Catalyst example code
and PV 4.2.


Regards,
Andy
