KSPSetMinimumIterations#

Sets the minimum number of iterations to use, regardless of the tolerances

Synopsis#

#include "petscksp.h" 
#include "petscmat.h" 
PetscErrorCode KSPSetMinimumIterations(KSP ksp, PetscInt minit)

Logically Collective

Input Parameters#

  • ksp - the Krylov subspace context

  • minit - minimum number of iterations to use

Options Database Key#

  • -ksp_min_it - Sets minit

Notes#

Use KSPSetTolerances() to set a variety of other tolerances

See KSPConvergedDefault() for details on how these parameters are used in the default convergence test. See also KSPSetConvergenceTest() for setting user-defined stopping criteria.
