The Tilt Pouring Tutorial for Altair Inspire Cast

Nicolas_Leiber

Hi! I have a question about the part used in the tilt pouring tutorial.

https://2021.help.altair.com/2021/cast/en_us/topics/cast/tutorials/tut_tilt_pouring_cast_c.htm#concept_orr_yd3_h2b

I'm not sure what the component in the simulation is supposed to be.
Does anyone know what this part is or what it's used for?

Thanks in advance!
