The new logic is more consistent with conventions. Function::operator[](uint i) now returns a reference to the sub Function. A Function keeps track of its sub Functions. Therefore, Function& u0 = u[0]; and plot(u[0]); do not involve copying a vector. u and u0 share the same vector. If a DofMap is renumbered after construction, the Function can make sure that all its sub Functions are modified accordingly. Likewise if the mesh is refined. Assignment makes a deep copy, i.e. you will get a new copy of everything. Therefore with Function u0 = u[0]; a new vector will be created and u0 will not change when u changes. What remains to be done is reseting the dof map for the reduced dimension of the subfunction and extracting vector components upon assignment. Eventually, for Function u0 = u[0]; GenericVector& x = u0.vector(); the vector x will only contains components related to the sub function u0. changeset: 6832:887eaeeb4e81b30cf5e2031c77bd2d77f1faed18 user: "Garth N.
