)

[pure virtual]

This method performs possibly repeated calls to the underlying linear solver's iterate() routine until the problem has been solved (as decided by the solver manager) or the solver manager decides to quit.

Returns:

ReturnType specifying:

• Converged: the linear problem was solved to the specification required by the solver manager.
• Unconverged: the linear problem was not solved to the specification desired by the solver manager
