Compute the local boundary Jacobian

Synopsis

#include "petscdmplex.h"   
PetscErrorCode DMPlexComputeBdJacobianSingle(DM dm, PetscWeakForm wf, DMLabel label, PetscInt numValues, const PetscInt values[], PetscInt fieldI, Vec locX, Vec locX_t, PetscReal t, PetscReal X_tShift, Mat Jac, Mat JacP)

Not collective

Input Parameters

• dm - The output DM

• wf - The PetscWeakForm holding forms on this boundary

• label - The DMLabel indicating what faces should be integrated over

• numValues - The number of label values

• values - The array of label values

• fieldI - The test field for these integrals

• locX - The local solution

• locX_t - The time derivative of the local solution, or NULL for time-independent problems

• t - The time

• X_tShift - The multiplier for dF/dxdot

Output Parameters
