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? Right; each new vector has a coefficient corresponding to each existing dof. > Now, I want to copy the solution (variables) to the vectors(added by > add_vector()), why do I need to create the local vector? You don't need to create anything to copy the solution to the new vectors. But if you want to copy the current_local_solution to the new vectors, it won't work, because the new vectors only have storage for local dof coefficients, not for ghost dof coefficients. --- Roy ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Libmesh-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/libmesh-users
