PCBDDCMatFETIDPGetRHS

Compute the right-hand side for a FETI-DP linear system using the physical right-hand side

Synopsis

#include "petscpc.h" 
PetscErrorCode PCBDDCMatFETIDPGetRHS(Mat fetidp_mat, Vec standard_rhs, Vec fetidp_flux_rhs)

Collective

Input Parameters

• fetidp_mat - the FETI-DP matrix object obtained by a call to PCBDDCCreateFETIDPOperators()

• standard_rhs - the right-hand side of the original linear system

Output Parameter

• fetidp_flux_rhs - the right-hand side for the FETI-DP linear system

Note

Most users should employ the KSP interface for linear solvers and create a solver of type KSPFETIDP.
