Detailed Description

Class to be thrown upon failing convergence of an iterative solver, when either the number of iterations exceeds the limit or the residual fails to reach the desired limit, e.g. in the case of a break-down.

The residual in the last iteration, as well as the iteration number of the last step are stored in this object and can be recovered upon catching an exception of this class.
