# PCPARMSSetLocal

Sets the local preconditioner to be used in `PCPARMS`.

## Synopsis

    #include "petscpc.h"
    PetscErrorCode PCPARMSSetLocal(PC pc, PCPARMSLocalType type)

Collective

## Input Parameters

- pc - the preconditioner context

- type - the local preconditioner type, one of

         PC_PARMS_LOCAL_ILU0   - ILU0 preconditioner
         PC_PARMS_LOCAL_ILUK   - ILU(k) preconditioner
         PC_PARMS_LOCAL_ILUT   - ILUT preconditioner
         PC_PARMS_LOCAL_ARMS   - ARMS preconditioner

## Options Database Keys

- pc_parms_local [ilu0,iluk,ilut,arms] - Sets local preconditioner

## Notes

For the ARMS preconditioner, one can use either the symmetric ARMS or the non-symmetric variant (ARMS-ddPQ) by setting the permutation type with PCPARMSSetNonsymPerm().

See the pARMS function `parms_PCILUSetType()` for more information.
