Reply To: Share Topology and Bonded contact

[Sampat Kumar]

1)Shared Topology essentially creates a 'bonded' or 'welded' connection between the surfaces where it is applied. Both the shared topology and bonded contact are similar but can't be the same, bonded contact has its own properties that make it different from shared topo. Shared topology and bonded contact are both connection methods, but they have distinct properties. Choosing between them depends on the specific model. In some cases, shared topology might be preferred over bonded contact, while in others, bonded contact might be more suitable. Ultimately, the most appropriate method depends on the specific application

Shared Topology and Bonded Contact are two different methods used for connecting parts in a simulation. Shared Topology does not combine two geometry parts into one part, but it tells the meshing algorithm that the two parts should share nodes at a common boundary, making the degrees of freedom continuous. This method does not allow for relative movement between the parts.

Bonded Contact is a contact setting that glues or bonds different parts together in the simulation. The two sides of the contact interfaces are meshed independently, so the degrees of freedom of the two parts are not continuous. This method provides users with flexibility in meshing the assembly and allows for each part in contact to be meshed independently. However, using contact may lead to some discontinuity or noise at the contact regions. You can follow the following link for more information.

2). After giving share topology, is there a possibility of giving any other type of contact too ? Like No separation, Frictional, etc. -
Answer- No, you can't provide.
