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.
