Previous: Setup:
-
Set convergence criteria. Convergence can be controlled by the
number of iterations, as well as various tolerances such as relative
residual, preconditioned residual, etc. Like all parameters,
reasonable defaults are used. Users are free to change these, though
care must be taken. For example, if an iterative method is used as a
preconditioner for a Krylov method, a constant number of iterations is
usually required.
-
Solve the system. This is just the
Solve()
routine.
