How to cite optistruct tutorials?

Hi, I'm working on a technical paper. I want to refer to a geometry of a tutorial document model. How do I cite your software and a tutorial model in it?

I want to cite the model of "OS-T: 2080 Hook with Stress Constraint" in "Altair Optistruct 2021 Tutorials."

I'm trying to cite this as an electronic book section, but I have no clue what should go into the author field, publisher field, and so on.
