NEPRIISetConstCorrectionTol#
Sets a flag to keep the tolerance used in the linear solver constant.
Synopsis#
#include "slepcnep.h"
PetscErrorCode NEPRIISetConstCorrectionTol(NEP nep,PetscBool cct)
Logically Collective
Input Parameters#
nep - nonlinear eigenvalue solver
cct - a boolean value
Options Database Keys#
-nep_rii_const_correction_tol
- set the boolean flag
Notes#
By default, an exponentially decreasing tolerance is set in the KSP used within the nonlinear iteration, so that each Newton iteration requests better accuracy than the previous one. The constant correction tolerance flag stops this behaviour.
