DMPlexComputeBdResidualSingleByKey#

Compute the local boundary residual for terms matching the input key

Synopsis#

#include "petscdmplex.h"   
PetscErrorCode DMPlexComputeBdResidualSingleByKey(DM dm, PetscWeakForm wf, PetscFormKey key, IS facetIS, Vec locX, Vec locX_t, PetscReal t, DMField coordField, Vec locF)

Not collective

Input Parameters#

dm - The output DM
wf - The PetscWeakForm holding forms on this boundary
key - The PetscFormKey indicating what should be integrated
facetIS - The IS giving a set of faces to integrate over
locX - The local solution
locX_t - The time derivative of the local solution, or NULL for time-independent problems
t - The time
coordField - The DMField object with coordinates for these faces

Output Parameter#

locF - The local residual
