Global Tie Constraint

Global Tie Constraint

Global Tie Constraint

(OP)
I have an assembly made up of lots of small parts. Is there a way to set a general tie constraint for all contacting faces instead of making lots of individual tie constraints for each face?

RE: Global Tie Constraint

You can use Find Contact Pairs tool to automatically find all contacting faces. Then change Type for all pairs to Tie constraint using the same tool.

RE: Global Tie Constraint

You can try this workaround:
Create a contact property with the behaviors Friction=Rough in tangential and No Separation in normal direction. Then define a General Contact and assign this behavior globally.

But be aware, that this only works when the faces are actually in contact. There is no Position Tolerance like in a Tie. But you can close small initial gaps when you create Contact Initialization definitions and global assignment.
