Interface for preconditioner variants that can be applied to quasi-Newton acceleration schemes.
Preconditioner that uses the recent residual to scale the quasi-Newton system.
virtual void _update_(bool timeWindowComplete, const Eigen::VectorXd &oldValues, const Eigen::VectorXd &res)
Update the scaling after every FSI iteration.
This class provides a lightweight logger.
