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.
