[Paraview] How to send data to ParaView Real Time

[Andy Bauer]

One possibility is ParaView Catalyst's live viz capability (
http://catalyst.paraview.org/). At this point I would consider it beta
functionality for it's intended purpose but it may be sufficient for what
you're trying to do. I'm attaching a Python script that you can demo it
with. You'll need to change the path to can.ex2 in the script to your local
location (it's available in ParaViewData in case you don't have it yet).
The directions on how to use it are:
1) <path to pv build dir>/bin/pvpython co_processing_3.py
2) run paraview and select Tools->Connect to Catalyst and click OK in the
next 2 pop-up dialogs
3) Select each filter under catalyst and then click on the circle/triangle
thingy to the left of it.
4) This should bring up the same filters under the builtin server. At this
point hopefully one of them will have a grayed out eyeball that you can
make visible to see the "simulation" in the ParaView client.

Now you should be able to make a new pipeline on the client to interrogate
that data. If this doesn't work, try quitting the ParaView client and
repeat. Like I said, it's beta functionality and doesn't include a test so
depending on which version of ParaView you're using you'll get different
results. I'm using master as of today so it's a bit clunky but it may work
really nicely with other versions.

Another possibility is the adios reader plugin. I don't know enough about
that though to give you any more information.

Regards,
Andy
