<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>I don’t recall seeing anything quite like that before. Are these boundaries in question those in the original simulation (noted by the file number) or the processes in your visualization (which can be annotated with the Process Id Scalars filter)? Does running the data through D3 help?<BR>

dataset using something like a clip plane or isosurface, the data seems<BR>
to be "slipped" (or offset) at each processor boundary - that is, there<BR>
appears to be a hard edge at each processor boundary. Unfortunately,<BR>
I'm not able to post an image that represents the problem.<BR>
<BR>
I'm not familiar with the Exodus data format, but it looks like it could<BR>
be an issue associate with ghost cells. Either there are no ghost<BR>
cells at the processor boundary layer, or they're possibly being<BR>
mismanaged? Curiously enough, this is the first time we've noticed<BR>
this problem after processing quite a few Exodus datasets. We're<BR>
using the latest production version of Paraview (3.4) and we've also<BR>
been able to duplicate the issue with other visualization tools, so we<BR>
think this is a problem with this particular Exodus dataset, if not the<BR>
Exodus format in general.<BR>
<BR>
Any ideas?<BR>
