DMPlexInsertTimeDerivativeBoundaryValues#

Puts coefficients which represent boundary values of the time derivative into the local solution vector

Synopsis#

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

Input Parameters#

  • dm - The DM

  • insertEssential - Should I insert essential (e.g. Dirichlet) or inessential (e.g. Neumann) boundary conditions

  • time - The time

  • faceGeomFVM - Face geometry data for FV discretizations

  • cellGeomFVM - Cell geometry data for FV discretizations

  • gradFVM - Gradient reconstruction data for FV discretizations

Output Parameter#

  • locX_t - Solution updated with boundary values
