Custom boundary conditions with identity pair

Please login with a confirmed email address before reporting spam

Hi,

I have a 3D model of a pile which is embedded within a cylinder representing the soil; both are thus modelled as solid mechanics. I have created the model using assembly, meaning I have identity pairs on the boundaries that are in contact.

What I want to achieve is to enforce compatibility and equilibrium only in the horizontal directions, by default continuity enforces all directions. I have not found a way to do so.

I have thought about using contact pair, however I want to remain in the frequency domain; which should be possible.

I did find a seemingly related thread on this discussion form on Google, however that page apparently does not exist anymore.

Thanks in advance!
