ABAQUS-Connection/Interaction

[Entherm]

What could be the best way to connect the 3D wire beam with the solid surface?

Initially, I tried using MPC Beam or Kinematic Coupling from the Interaction module but I am not getting expected results from these constraints.
There is some space between the two plates.

Distributing coupling constraint seems like the best choice for me. There's even a similar example of connection in Abaqus documentation (chapter "Copupling constraints", paragraph "Dimensional coupling"). Several tests were carried out to verify the accuracy of such connection.

Thank you @FEA way. I tried using continuum coupling but I got the following shape and this is not as expected. It looks like the wire beam is breaking from the connection. I have NLGEOM on and nonlinear material property. It seems like the breaking kind of behavior occurs in the nonlinear range.

You can also try using rigid body constraint, maybe it will give better results than couplings in this case.
