Is there any way other than share topology to create node to node connectivity ?  (May be using some types of contacts and selecting particular options in contacts)

Thanks in advance

Hi Deepesh,

Could you describe what is your objective for creating such a contact pair? Are the two objects in contact supposed to remain connected to each other throughout the analysis?

[deepesh.p.gurdasani]

Yes. I want two objects to remain in contact throughout the analysis.

Thanks Deepesh.

If you expect no relative motion between the objects, you can first define a contact pair and then set the Type to Bonded (see the screenshot below).

But normal 'Bonded' won't create node to node connectivity.

For the bonded contact, the Mechanical solver searches for the nodes within a "pinball region" and then no penetration, no separation, and no sliding is allowed between those faces or edges. If you need the nodes of the two surfaces to merge at the interface, you can use shared topology. Check if the following document is helpful to you:

What I mean to ask was, is there any other way (If share topology is not possible) of giving contact that can replcate share topology's effects (Similar if not same) ?
