Ok, thanks! However, (a) Why is f not a discrete function? (It is defined on a finite element space?) (b) I would very much like this not to give an error, but rather work ;) I would use something like this all the time when checking convergence. -- Marie > Garth > >> -- >> from dolfin import * >> >> mesh = UnitSquare(1,1) >> V_h = FunctionSpace(mesh, "CG", 1) >> f = Function(V_h, "1.0") >> >> Q_h = FunctionSpace(mesh, "DG", 1) >> Pi_f = interpolate(f, Q_h) >> >> r = norm(Pi_f) >> print "r = ", r >> --- >> >> -- >> Marie >> >> >> _______________________________________________ >> DOLFIN-dev mailing list >> DOLFIN-dev@fenics.org >> http://www.fenics.org/mailman/listinfo/dolfin-dev > > _______________________________________________ DOLFIN-dev mailing list DOLFIN-dev@fenics.org http://www.fenics.org/mailman/listinfo/dolfin-dev
