1) In the geometry, make the solid and beam touch
2) In the physics menu, add multipysics
3) right click on the multiphyics node and add "Solid Beam Connection"
4) make a fine mesh around the connection
I found that I had to remake the Solid Beam Connection if the topology changes. I also found it tricky to get solver convergence in some circumstances

Hi,
If you are using the beams as reinforcement bars inside the concrete, the best method is to do exactly as in
https://www.comsol.com/model/concrete-beam-with-reinforcement-bars-10440
Note that you must constrain the beam from rotation around its own axis somewhere, in order to avoid a singular stiffness matrix.
The Solid Beam Connection is not intended for this situation.
Regards,
Henrik
