This tutorial is essentially a mixture of step-40 and step-41 but instead of PETSc we let the Trilinos library deal with parallelizing the linear algebra -(like in step-32). Since we are trying to solve a similar problem like in +(like in step-32). Since we are trying to solve a similar problem like in step-41 we will use the same methods but now in parallel. Another difficulty is the handling of the different constraints from -(the dirichlet conditons), the hanging nodes and the inequality condition that -arises from the contact. For this purpose we create three objects of type +(the dirichlet conditons), the hanging nodes and the inequality condition that +arises from the contact. For this purpose we create three objects of type ConstraintMatrix. Beside the ConstitutiveLaw class there is another new class called Input. This class allows us to read in an obstacle from a file.
