  I want to define the resistance between two contact surfaces, but I encountered some problems while defining the curve. How is the variable resistor represented in the keyword that DEFINE FUNCTION? Can you please tell me how to set the resistance curve, or provide relevant tutorial videos or examples?

  Hi
  This paper shows in detail how to define the contact and the function.
