NX 3D FEA with 2 Bodies

Experimenter
Experimenter

Hi, 

 

I'm a new user of FEA and I am wondering how I can model the forces and displacements on 2 interacting bodies. Whilst running and solving currently the forces only affect the body that the constraints are on and not the other body. Im wondering whether I've it is because ive got the constraints, mesh or loading wrong. I have attached my files, if you could help me i would be very grateful. 

 

For contest im trying to do an FEA analysis on rail wheel and track interface as shown in the paper attached. 

Thanks, 

Tobi.
