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

• 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
