Hi, I have a student starting work on a project that entails PV+Catalyst as an in situ endpoint.
My specific question is “where are the docs for Catalyst”, including sample code.
This web page – [https://www.paraview.org/Wiki/ParaView/Catalyst/Overview](https://www.paraview.org/Wiki/ParaView/Catalyst/Overview) – seems to have not been updated since 2016 ☹
I do see [Catalyst — ParaView Documentation 5.12.0 documentation](https://docs.paraview.org/en/latest/Catalyst/index.html), which seems somewhat more up to date, including what appear to be some useful examples here [Examples for Simulation Developers — ParaView Documentation 5.12.0 documentation](https://docs.paraview.org/en/latest/Catalyst/examples.html) though the couple of examples I peeked at were \>= 3 yrs old, so maybe there is more up-to-date information elsewhere.
Thanks in advance.

Your last two links are the correct ones.
The examples listed are in the ParaView source code at Examples/Catalyst2. In the source code are a few more not linked in the page you listed. They are tested so they should be up to date.
Another useful link is
[https://catalyst-in-situ.readthedocs.io/en/latest/introduction.html](https://catalyst-in-situ.readthedocs.io/en/latest/introduction.html)
As explained in those pages, Catalyst is the protocol while ParaView Catalyst is the implementation of the protocol. There is an Ascent implementation of the Catalyst protocol as well.
Hope it helps,
Dan
