| ksp | - iterative context
|
| n | - iteration number (not used)
|
| fnorm | - the current residual norm
|
| dummy | - some context as a C struct. fields:
coef: a scaling coefficient. default 1.0. can be passed through
-sub_ksp_dynamic_tolerance_param
bnrm: norm of the right-hand side. store it to avoid repeated calculation
|
Notes
This may be useful for a flexibly preconditioner Krylov method to
control the accuracy of the inner solves needed to gaurantee the
convergence of the outer iterations.
