  1. Void property is only compatible with void material.
  2. An optional format is available.
  3. This additional data allows to define contact interfaces with void material and property: all kinds of input for interfaces will then be available (Igap =1, Stfac as a stiffness factor).
  4. Contact stiffness will be correctly calculated only when Thick is entered. If there is no thickness entered, the elements with this property will have no contact stiffness.
