KSPGetTotalIterations#

Gets the total number of iterations this KSP object has performed since was created, counted over all linear solves

Synopsis#

#include "petscksp.h" 
PetscErrorCode KSPGetTotalIterations(KSP ksp, PetscInt *its)

Not Collective

Input Parameter#

  • ksp - the iterative context

Output Parameter#

  • its - total number of iterations

Note#

Use KSPGetIterationNumber() to get the count for the most recent solve only If this is called within a KSPSolve() (such as in a KSPMonitor routine) then it does not include iterations within that current solve
