SNESGetLinearSolveIterations
Gets the total number of linear iterations used by the nonlinear solver.
Synopsis
#include "petscsnes.h"
PetscErrorCode SNESGetLinearSolveIterations(SNES snes,PetscInt *lits)
Not Collective Many br
Input Parameter
snes -SNES context Many br
Output Parameter
lits -number of linear iterations Many br
Notes
This counter is reset to zero for each successive call to SNESSolve() unless SNESSetCountersReset() is used. Many br
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 Many brthen call KSPGetIterationNumber() after the failed solve. Many br
