Alan,
If you are working on your own data, the LIC plugin expects velocity to be
point centered rather than cell centered. If you do it on cell centered data,
you'll get just uniform streaks without anything interesting happening.

Hi,
One of our users is running a very big simulation and writing out images of two
slices (two different views) every 1000 iterations and writing out the data for
the two slices (two different data writers) as VTK files every 5000 iterations.
It is using Paraview 4.4.

Hello again,
I'm (finally) trying to get Catalyst to successfully link to our application
code on Excalibur (Cray, ARL HPC). I was able to build paraview and all of the
dependencies thanks to help I've gotten on the list here in the past. However,
when I try to link my code to it (and this is
doing the whole build from
scratch, I'd suggest you just search for the ParaViewConfig.cmake file to find
where PV was actually built and just point to that.
