DMPlexInsertBoundaryValues#

Puts coefficients which represent boundary values into the local solution vector

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexInsertBoundaryValues(DM dm, PetscBool insertEssential, Vec locX, PetscReal time, Vec faceGeomFVM, Vec cellGeomFVM, Vec gradFVM)

Not Collective

Input Parameters#

  • dm - The DM

  • faceGeomFVM - Face geometry data for FV discretizations

  • cellGeomFVM - Cell geometry data for FV discretizations

  • gradFVM - Gradient reconstruction data for FV discretizations

Output Parameter#

  • locX - Solution updated with boundary values
