Hey again,
Okay, I just saw a partial answer on the ParaView FAQ "Why can't I
change the filename on my reader?".
If other people have a similar situation, though, with trying to set
up and change files using a "template" for a more complicated,
multiple-file visualization, I'd appreciate it if you could share your
techniques for making this as easy as possible for the user.
Thanks,
-Eric

Hey All,
My group wants to use ParaView for debugging their simulation
system, where they might output many different files in a day with
tweaked parameters and want to quickly view the results to see
whether things are changing the way they expect.
The problem is that for each run there are three different output
(unstructured grid) files, and to make a nice visualization each has
to be glyphed or colored or filtered in some special way. I can do
this, and it looks great, but it takes a while to set up each time a
new set of files is generated, so it's a bit of a pain.
Therefore, main question: Once a visualization pipeline is set up,
is there any easy way to pick new files for the readers so new data
could quickly be visualized using an existing "template"?
I have tried reading in new files and using the "Change Input..."
menu item, but it's a bit of a pain because it's a multi-step method
that changes the order of items in the Pipeline Browser each time
you do it. I know how to save a state file and then edit the source
file names for the readers, but this takes the user out of ParaView
and is a little clunky, but do-able. I can also write a python
script that loads a state file and changes the input files and
creates an animation automatically, but that isn't as flexible as
looking at the data in ParaView itself. (I also tried to change a
source file name from the Python shell within ParaView, but at least
with an Xdmf file, that always crashes ParaView when I'm driving...)
Am I missing something clean and easy? Is this a typical thing
people would want to routinely do with ParaView?
Thanks,
-Eric
