[David Fuentes]

*Is there a way to pass the boundary set id to the function pointers for
the residual evaluation on the boundary ?*

*I want to pass the boundary condition/constraint ID (ids):  PetscErrorCode
PetscDSAddBoundary(PetscDS ds, DMBoundaryConditionType type, const char
name[], const char labelname[], PetscInt field, PetscInt numcomps, const
PetscInt *comps, void (*bcFunc)(void), PetscInt numids, const PetscInt
*ids, void *ctx)*

*to the functions for the residual evaluation on the boundary.*


*For example, I have two side sets in an exodus file. I want to implement
Neumann boundary conditions on side set = 2 and Mixed/Cauchy BC on side set
= 3. Or similarly use different*

*gmsh BC tags for Neumann/Mixed BC.*
