Conveyor Vacuum Belt modelling

Hi there!

I am trying to modellize a vacuum stacker for virtual commissioning but I don’t know how to modellize and simulate the suction procedure. This procedure can be seen on the following videos, if you have time:
minute 00:20-00:30: EDF Vacuum Stacker with Apstar HG2 RDC Line - YouTube

minute 01:03-01:30 Apstar Hg2 1628 with automatic peripherals - Edf Europe - YouTube

As you can see, the product is transported on a conveyor until it is sucked to the vacuum conveyor belt, and it is finally thrown to a pallet (or to another conveyor in the second video).

Thanks in advance and if you need more information please ask.
