[Paraview] Error with EnSight6 reader with "transient single file format" and "scalar per element" variable

[David Luet]

Hi Berk,
Thanks for your answer. I am pretty sure that there is a bug in the reader.
Specifically in the file vtkEnSight6Reader.cxx. I have modified the source
and now the problem is fixed. I have attached a patch to correct the
problem. Could you include this patch if not in the 3.12 version at least
in the next RC? We have users of our solver who need Ensight6 reader.
Thanks,
David
