KSPCheckSolve#
Checks if the PCSetUp() or KSPSolve() failed and set the error flag for the outer PC. A KSP_DIVERGED_ITS is not considered a failure in this context
Synopsis#
#include "petscksp.h"
PetscErrorCode KSPCheckSolve(KSP ksp, PC pc, Vec vec)
Collective on ksp
Input Parameters#
ksp - the linear solver (KSP) context.
pc - the preconditioner context
vec - a vector that will be initialized with Inf to indicate lack of convergence
Notes: this may be called by a subset of the processes in the PC
Developer Note: this is used to manage returning from preconditioners whose inner KSP solvers have failed in some way
