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
