Self contact during deformation using Partitions

Description:

Hello, I have been working on the simulation of a deformable tire. Previously I have made a post regarding the contact of the wheel with a rigid surface. (https://community.altair.com/discussion/62772/how-to-find-deformation-of-loaded-wheel-on-rigid-surface#latest)

Now I am stuck on a new problem:

For the self contact of the flexible wheel I want to use the partition tool, each partition can then be assigned a separate motion contact with the part it will come in contact with during deformation.

The partition should still be fully connected to the main body of the wheel. In my simulations, a very oversimplified model to understand the process, I have connected the parts using locked joints. This does seems to be working as the parts are still connected, but the deformation is not what it should be. The joints put some kind of extra constraint on the partition which prevents the two parts as acting as one body where the deformation plot would be continuous.

How can I change the connection between main body and partition to have them act as one, but allow for defining self contact within the model?

Kind regards,

Tim
