Hi Joe, I've seen this before and there is a bug report in mantis here:
http://www.paraview.org/Bug/view.php?id=13382 There has also been a patch posted to the vtk-developers list a while back although I haven't tested it: http://markmail.org/message/zg3damrg27p5sgue Regards, Paul On 10 October 2014 00:32, Insley, Joseph A. <[email protected]> wrote: > Hi, > > I have a serial vtu dataset provided by one of my users.
