DMPlexInsertBoundaryValuesFVM

Reconstruct cell gradients and insert non-essential (e.g. outflow) boundary values into a local finite-volume solution vector.

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexInsertBoundaryValuesFVM(DM dm, PetscFV fv, Vec locX, PetscReal time, Vec *locGradient)

Collective

Input Parameters

• dm - the DMPLEX

• fv - the PetscFV discretization

• locX - the local solution vector; updated with non-essential boundary values

• time - the current time

Output Parameter

• locGradient - if non-NULL, the local vector holding the reconstructed cell gradients

Note

The caller receives ownership of *locGradient via DMGetLocalVector() and must return it with DMRestoreLocalVector().
