I believe the generate normals option requests a layer of ghost cells. Are you sure your reader is responding properly to that?<BR>

I have encountered a problem with the contour filter with computer<BR>
normals set on.<BR>
<BR>
My configuration is a Red Hat Enterprise Linux Server release 5.4<BR>
(Tikanga) server running 32 pvserver processes, openmpi 1.4.1, Mesa<BR>
7.6 (OSMesa).<BR>
a Fedora release 11 (Leonidas) workstation running the client.<BR>
Both are CVS ParaView-3-8 builds updated after the calculator fix was<BR>
applied (very fast thank you).<BR>
<BR>
I load a dataset with 2 vectors and a scalar all floats using VPIC reader.<BR>
I run 1 of the vectors through the calculator to compute magnitude.<BR>
Result array has range [.250244, .572473]<BR>
I then run that result into a contour, which will do 1 of 2 things:<BR>
If I un-check compute normals : contour works as expected (attached).<BR>
If compute normals is checked :<BR>
it takes a long time to produce a bad contour (attached) with<BR>
errant lines OR the server segfaults<BR>
<BR>
If the server segfaults it is worthy of note that the information tab<BR>
of the Calculator then reports the Result array as having<BR>
range[0.0,3.57...+38]<BR>
If I delete the contour and the calculator, create a new calculator,<BR>
calculate magnitude it reports range as [0.0,3.57...+38]<BR>
<BR>
Seems like a problem ...<BR>
<BR>
I will work at finding a more simple example...<BR>
<BR>
Thanks,<BR>
