The Simulia User Assistance documentation claims you can follow these instructions to find additional plug ins, but I'm not having any success in doing so. primarily, I do not see a "process automation" filter.

Additional plug-ins are available in the https://www.3ds.com/products-services/simulia/simulia-academic-program/learning-community/, which provides example plug-ins as well as access to a community of users that fosters the advance of the Abaqus Scripting Interface and the Abaqus GUI Toolkit. Click Blog and filter by Process Automation to browse plug-in examples in this community. You can also write your own plug-ins, as described in the rest of this chapter.
