Hi Andy!

Brep models for instance implicitly contain contact information afaik. For the rest you would have (for now) have to define the contacts manually but we are already working on a solution for this, also see **[Automatic Contact Detection](https://www.simscale.com/forum/t/automatic-contact-detection/73288)**.

Cheers,

Jousef
