Roy, I have a question related to this. Since PetscVector does not provide a const version of vec(), what do you do when all you have is a const PetscVector, for example in the residual/assembly but want to access the vec() explicitly ? Petsc does not have any "const" qualifiers and so this needs a hack like const_cast. Is there a good suggestion to get around this ?
