KSPFETIDPSetInnerBDDC#

Provides the PCBDDC preconditioner used to set up the KSPFETIDP matrix for the Lagrange multipliers

Synopsis#

#include <petscksp.h> 
PetscErrorCode KSPFETIDPSetInnerBDDC(KSP ksp, PC pc)

Collective

Input Parameters#

Note#

A PC is automatically created for the KSPFETIDP and can be accessed to change options with KSPFETIDPGetInnerBDDC() hence this routine is rarely needed
