  Hi,
  
  I need to specify contact between two lines in two surfaces using APDL code. I know how to do it using the "contact manager" but I want to know how to do it using apdl code.
  
  Lets say the target line number is "1", and contact line number is "2". And the friction coefficient coefficient between the contact is 0.1
  
  Thank you.

  here is an example:
  
  et,1,175 ! Contact element
  
  et,2,170 ! Target element
  
  mp,mu,1,0.1 ! Material 1 - Friction coefficient = 0.1
  
  lsel,s,,,1 ! Select Line 1
  
  nsll
  
  type,1
  
  mat,1

  See Chapter 5 of the Contact Technology Guide in the APDL manual.
  
  You could use selection logic and contact 177, target 170 elements in 3-D.
