PASS’s primary purpose is to make the implementation of a Material Handling in your Digital Twin or Virtual Prototype as quick-, painless- and verifiable as possible. Depending on whether you’re looking to preview your process flow or validate your control models you will want to use different tooling.
Discrete Event Simulation (DES)
When working on a preview setup-, or when only (production) process variation- and timing is relevant you will want to use Discrete Event Simulation (DES). DES is what a mechanical engineer would call - Kinematic - meaning ‘Simulating Motion without considering Force’. Arguably this way of simulating moving parts is more akin to creating a standard 3D animation: the transformations and material interaction are continuously calculated over a set of paths in the 3D world (called Splines).

Alternatively, when working to validate models that control your real-time material handling you will want to make use of ‘Field for Accurate Contact Testing’ (FACT) regions. FACT is designed to work in tandem with the Unity Physics System - and offers you the ability to ‘exclude’ a region in your scene from that engine to run calculations in more detail, or track and export physical motion in detail in said region.
[Note : FACT is currently still in Pre-Alpha, and only open for testing in internal Prespective Projects, eta. for Alpha release is May 2021]
