Detailed Description

MonolithicRobinInterface - Class for the Robin coupling of etherogeneaous problems.

Author

Paolo Crosetto

This class is a base interface for the monolithic Robin coupling of 2 problems. A coupled Dirichlet-Neumann problem can be transformed into a Robin one by inheriting from this class. The allocation of the memory for M_robinCoupling has to be done outside.

The Robin conditions are obtained algebraically through linear combination of the lines corresponding to the Dirichlet and Neumann coupling conditions already present in the matrix. This is achieved by multiplying the matrix times a restriction matrix (M_robinCoupling) which performs the restriction to the interface and the linear combination. Then the result is summed to the original matrix. The update of the rhs vector must be done outside this class.

Todo:

Remove this class and try to implement the same coupling otherwise.
