 Create FETI-DP operators

Synopsis

#include "petscpc.h" 
PetscErrorCode PCBDDCCreateFETIDPOperators(PC pc, PetscBool fully_redundant, const char *prefix, Mat *fetidp_mat, PC *fetidp_pc)
Collective

Input Parameters

pc - the BDDC preconditioning context (setup should have been called before)
fully_redundant - true for a fully redundant set of Lagrange multipliers
prefix - optional options database prefix for the objects to be created (can be NULL)

Output Parameters

fetidp_mat - shell FETI-DP matrix object
fetidp_pc - shell Dirichlet preconditioner for FETI-DP matrix

Notes

Currently the only operations provided for FETI-DP matrix are MatMult and MatMultTranspose
