Dear Roy: I don't sorry that I don't understand the second problem. To my knowledge, if I use add_variable() to add the variables, these variables will add dofs, right? If I use add_vector() to add the vectors, I don't specify the purpose of the vectors and they don't add dofs, right? Now, I want to copy the solution (variables) to the vectors(added by add_vector()), why do I need to create the local vector? why not just use the vectors added by add_vector()？ it doesn't work? thanks a lot.
