PCAIRSetCInverseSparsityOrder

Sets the power of the operator matrix used as the sparsity pattern of assembled PCAIR C-point approximate inverses

Synopsis

PETSC_EXTERN PetscErrorCode PCAIRSetCInverseSparsityOrder(PC pc, PetscInt input_int)

Logically Collective

Input Parameters

• pc - the PCAIR preconditioner context

• input_int - the power of the operator matrix used as the sparsity of assembled inverses for the C-point smooth

Options Database Key

• -pc_air_c_inverse_sparsity_order sparsity_order - the power of the operator matrix used as the sparsity of assembled inverses for the C-point smooth; if unset, defaults to the same as -pc_air_inverse_sparsity_order
