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 <bool> | - 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.
