I am working with a simplified railway model. I wish to couple a beam with the 3D model structure of the rail and to apply a moving (depends on time) force on a surface, by means of the command "Boundary Load".
I tried to connect the beam with the solid model with the "Prescribed displacement" command on the first node of the beam setting the average values of u,v,w of the facing surface of the 3D model structure and the rotation through the curl of displacement, as Ivar Kjelberg suggested.
If I try to simulate a stationary study, with a boundary load applied, it works.
Otherwise if I try to apply a moving force (by means of the definition of a square wave dependent on time), it does not work and the solver has big problems gets stuck.
(I used a fully coupled solver)
Thank you in advance
Emanuele
