PCAIRSetCInverseType

Sets the type of approximate inverse used as the PCAIR C-point smoother

Synopsis

PETSC_EXTERN PetscErrorCode PCAIRSetCInverseType(PC pc, PCPFLAREINVType inverse_type)

Logically Collective

Input Parameters

• pc - the PCAIR preconditioner context

• inverse_type - the approximate inverse type, one of PFLAREINV_POWER, PFLAREINV_ARNOLDI, PFLAREINV_NEWTON, PFLAREINV_NEWTON_NO_EXTRA, PFLAREINV_NEUMANN, PFLAREINV_SAI, PFLAREINV_ISAI, PFLAREINV_WJACOBI, or PFLAREINV_JACOBI

Options Database Key

• -pc_air_c_inverse_type (power|arnoldi|newton|newton_no_extra|neumann|sai|isai|wjacobi|jacobi) - the approximate inverse type used for the C-point smooth; if unset, defaults to the same as -pc_air_inverse_type
