One should generally continue iterating until a suitable relative (or absolute) residual norm is reached, with correspondingly small Newton stepsize norm (for nonlinear problems). Reaching the max number of linear solver iterations before one of these other goals is achieved is probably best treated as a failure in a linear problem. The max number of iterations is just there to control how long you are willing to wait for an answer... -- John ------------------------------------------------------------------------- Sponsored by: SourceForge.net Community Choice Awards: VOTE NOW!
