The contacts regions for each subdomains are defined below.
Let us consider two domains D1 and D2, having some elements in contact and denote with N1 and N2 the first and the 
last nodes of the contact region for D1, and with N3 and N4 the first and the last nodes of the contact region for D2.
For this situation the values below have to be given:

      *CONTACT
       D1      D2
       N1      N2      N3      N4
