PCBDDCMatFETIDPGetSolution

Compute the physical solution using the solution of the FETI-DP linear system

Synopsis

#include "petscpc.h" 
PetscErrorCode PCBDDCMatFETIDPGetSolution(Mat fetidp_mat, Vec fetidp_flux_sol, Vec standard_sol)

Collective

Input Parameters

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

• fetidp_flux_sol - the solution of the FETI-DP linear system`

Output Parameter

• standard_sol - the solution defined on the physical domain

Note

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