[Paraview] Warning about Version while Reading File

[Fastl, Thomas]

Hello,


I'm really sorry for the confusion: When writing a file using ParaView I obtain 4.0 in the header, but I had a script to generate file from Matlab and for some reason I wrote 4.2 in the header of all my files. This didn't cause any problems with an older version of ParaView 4.2.0, but throws a warning in ParaView 5.0.0. Problem solved and sorry again, that was unnecessary....!


Best, Thomas

Hi Thomas,
I am surprised that version 4.2 gets in the file. In our last upgrade to the file format we increased the version from 3.0 to 4.0.
So format 4.2 is not out yet. I wonder if Paraview writes that.

How did you generate the file?

Thanks,
Dan

Actually, we changed how the ghost levels are handled and had to update the format accordingly. It may be related to that. Dan would know more.

Thomas,

I'm surprised your file didn't cause a complaint in ParaView 4.2. The
legacy VTK file reader in VTK hasn't changed in quite some years. What
software writes your VTK file? If it were written with VTK (perhaps by
way of ParaView), the file version number should be 4.2.

By the way, this shouldn't be a problem other than annoying you with
the warning message.
