[petsc-users] Jacobian construction, DA vs Plex

[Tobin Isaac]

Hi,

If I have a pointwise Jacobian function f, I know that I can call
DMGetDS() and pass f to PetscDSSetJacobian(), and that f will be used
by PetscFEIntegrate() and thus by DMPlexSNESComputeJacobianFEM().  It
looks like PetscFEIntegrate() is only used by plex and not da.  Is
there anyway that I can use f to construct a Jacobian with a da
object?
