NEPRIISetConstCorrectionTol#

Sets a flag to keep the tolerance used in the linear solver constant.

Synopsis#

Logically Collective

Input Parameters#

  • nep - the nonlinear eigensolver context

  • cct - a boolean value

Options Database Key#

  • -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 behavior.
