Tutorial and exemples for liggghts

Hello,

We are a very small french research team. And we plane to study the processus of additive manufacturing. The first step is to model the flow of particles on the system. We encounter a few difficulties to understand the behaviour of the software, the underlying physics and we would like to found a easy step by step tutorial and caracteristics examples.

Could you give us some advices to find such sort of documentations and code examples?

Thanks so much,
