Hello again,
The Catalyst C and C++ examples all require the python script
as an argument at run time. The Fortran example requires that
the script be in the same directory. So when you aren't giving
the script as an argument, the code is running but doesn't have
any information about what to co-process, and it exits doing nothing.
I did provide the script as an argument (following the instructions
at the top of the python script).
As for the seg fault, my guess is that the ParaView versions of
the python script and the one against which you are compiling
are different. I know they are different on mine and while I don't
get a seg fault, I get some errors about the VTK class structures.
I'm not quite sure what you mean by "ParaView versions of the python
script". I do know that when I compiled the simulation with the
Catalyst code, I am pointing to the same version of ParaView that
I'm running. I don't know how that correlates to python versions.
I would recommend also checking out the latest versions of the examples.
Andy has done a lot of work on them recently, so if they are even a few
weeks old, they might not work as expected. Also, you could just export
a new script with the PV version built on your system.
Well, thought I was downloading his latest examples by grabbing
them directly from his github page. Is there somewhere else to
look for them? Most of the files are dated May 13, 2013.
I hope this points you in the right direction.
Not yet, but if you could explain what you mean by the ParaView
python version, that might shed some light. I know I'm using the
same version of ParaView.

Thanks for the suggestions,
Bill

Subject: [Paraview] Attempting to run Catalyst CFullExample
Hello,
I'm in the process of attempting to learn how to use the Catalyst
feature of ParaView, and I have a problem.
I found the sample code on github:
- https://github.com/acbauer/CatalystExampleCode
and I began by compiling the "CFullExample" application.
There is some weirdness when trying to compile the application
as a non-Catalyst simulation, but since I'm trying to learn
Catalyst, that's just an aside to the code maintainers.
So I have the application (FEDriver) compiled, and there is
a sample python script. I ran ParaView (same version as I
used when compiling FEDriver -- a git clone from April),
and I start the Catalyst connection:
-> Tools -> Connect to Catalyst
(which I had to find by poking around, the SC'12 Catalyst
tutorial doesn't seem to mention this -- or not that I noticed.
An aside to the code documenters.)
So I followed the instructions in the python script, and
with ParaView accepting Catalyst connections on port 22222,
this is what happens:
% ./FEDriver SampleScripts/feslicescript.py
Segmentation fault (core dumped)
Actually, that happens regardless of whether ParaView is running
or not, but it only happens when I give the python script as an
argument -- w/o the script, it runs for a moment and then returns
to the prompt.
So what am I missing?
Thanks,
Bill
