Hello @zauser519 and thanks for trying Catalyst!

You should probably start with [How to try out Catalyst2](https://discourse.paraview.org/t/how-to-try-out-catalyst2/9008) guide where you can find some explanation and tutorial to start with catalyst.

If you still encounter some difficulties, please share more informations about the simulation you are connecting at, and the script you are using.
