Hi Zoltan,

Could you please elaborate your question?

[Zoltan Wagner]

Hi

So basically this inner core is built up from individual smaller cores and as these structure is compressed it folds in, meaning the sides and edges touch. I can't define contact as there is only one geometry but for my project I have to define self contact?

[Ankush Choudhary]

Hi,

As I can't see the geometry here, it is difficult to say how you want to generate the contacts. However, for creating a self-contact, you can define the contact and target to the same surface or an edge. For further information, please watch this video.

This is one of the individual cores and a massive one is buitl from this. So when the entire structure is compressed the inner walls touch. In my simulations I haven't defines anything so the walls just go through each other.

Thanks

Hi,

If you define contact on one surface and target another, contact compability will occur under compression.

[Zoltan Wagner]

That's great thank you. is there an easy way of doing it as i have 96 of these structures put together

[Ankush Choudhary]

If there is complete compression, you can try self-contact as well.

[Zoltan Wagner]

Yes that is what i need to do, do you have a video or a tutorial on how to do that?

[Ankush Choudhary]

I don't have the tutorial related to it, but you can create a self-contact by making contact and target the same surface.

Zoltan, if you solve this model in Explicit Dynamics, self contact is automatically created for you by the solver so you don't need to manually create any contacts.
