Wheel-rail contact in Ansys

  Hello!
  I am a mid-beginner in Ansys. I want to simulate wheel - rail contact in order to get results of pressure in contact path. I want to simulate wheel rotation with creepage forces. Additonaly I want to simulate slip (creepage) beetwen wheel and rail by moving rail towards wheel.
  In order to make a good simulation, I want to gain knowledge and experience from you, so I have following questions:
  in which environment should I simulate- Transient or Explicit Dynamics or LS Dyna?
  should I make a contact between wheel and rail in CAD or by Ansys contact settings by chosing faces, edges, etc.?
  how to deal with contact phenomenon? Is it necessary to use APDL commands? The wheel-rail contact is highly compliaced issue...
  
  I would be very thankful for your help :)
  
  Best regards,
  Martin

  check the following link for an initial idea on how you can simulate an wheel and bump and from here you can start to build your rail wheel model.
