I am not sure about my command is correct, can you check with that?
My command line is /usr/local/bin/mpiexec -np 2 ./CFullExample script.py.
I always come across some socket errors a the end of live visualization.

Just to confirm, you are getting some socket errors in ParaView **after** simulation has completed? In that case, it’s safe to ignore them. They are just printed out to indicate the connection has been terminated. Are there any other problems you’re noticing. BTW, is is not a good thread to have this conversation on.

Thanks for replying quickly!
But the problem is that the animation the catalyst shows is kind of wired and not the correct one.
And when I test the catalystlive function with the command ctest -R CatalystLive, it always stop at the second test and no response any more.

Hi folks, this is the description for the In Situ Support category. Please take the conversation over to [Catalyst live visualization](https://discourse.paraview.org/t/catalyst-live-visualization/967/15)
Thanks.
