Thanks for your reply. 

The warnings are:

1: SECTION_SHELL(ID: 1): thickness is less than 0.5. Refby 2 parts: 1 2..... warning(2)
1: ELEMENT_BEAM(ID: 2449): Beam distance is too small..... warning(47177)
 
For beam-to-beam contact, the contact should be created for each beam part. Say if I have three different beams interact with each other, I will create three contacts, right? 
 
Another question: for discrete beams(form 6), what is the best material to be assigned to act as a nonlinear spring with one axial DOF? 
ThanksÂ
