SNESGetLinearSolveIterations#

Gets the total number of linear iterations used by the nonlinear solver in the most recent SNESSolve()

Synopsis#

#include "petscsnes.h"  
PetscErrorCode SNESGetLinearSolveIterations(SNES snes, PetscInt *lits)

Not Collective

Input Parameter#

  • snes - SNES context

Output Parameter#

  • lits - number of linear iterations

Notes#

This counter is reset to zero for each successive call to SNESSolve() unless SNESSetCountersReset() is used.

If the linear solver fails inside the SNESSolve() the iterations for that call to the linear solver are not included. If you wish to count them then call KSPGetIterationNumber() after the failed solve.
