***ERROR: The requested number of domains cannot be created due to
          restrictions in domain decomposition. The following limitations may
          be helpful in understanding this behavior: 

 1. Contact pair requires that the surface nodes be in the same domain.

             In the case of kinematic contact, elements associated with

             the surface facets must also be in the same domain.

          2. An adaptive mesh domain must be contained within a single

             parallel domain. Nodes on the boundary between an adaptive

             mesh domain and a nonadaptive domain must not be shared

             with other parallel domains.

          3. All the nodes involved in a kinematic constraint must

             be in the same domain and must not be shared with other domains.

          4. Nodes associated with beam elements whose center of mass

             does not coincide with the location of the beam node or which

             use the *BEAM ADDED INERTIA option must be within a single domain.
