PCPFLAREINVSetReusePolyCoeffs

Controls whether PCPFLAREINV reuses its stored polynomial coefficients on the next setup

Synopsis

PetscErrorCode PCPFLAREINVSetReusePolyCoeffs(PC pc, PetscBool flg)

Logically Collective

Input Parameters

• pc - the PCPFLAREINV preconditioner context

• flg - PETSC_TRUE to skip recomputing the polynomial coefficients on setup when the nonzero pattern is unchanged

Options Database Key

• -pc_pflareinv_reuse_poly_coeffs (true|false) - skip recomputing the polynomial coefficients during setup when the matrix has the same nonzero pattern; defaults to false
