Dear All,
I am currently dealing with hanging support points in my problem and I have
a couple of questions. These are:
1. For my case, different elements of the mesh have different polynomial
orders of the basis. Due to support points at the element edges, I believe
there will be hanging support
Thanks Wolfgang.
I think it would be helpful if there was something about it in
documentation.

Marek,
One more thing. Because the domain is curved, you will need to attach
a manifold to the Triangulation
(http://dealii.org/8.4.1/doxygen/deal.II/step_53.html) So that when
you refine your mesh, the new points on the boundary are put at the
right place.
Best,

Yes, but I have thought, that for a programmer it is easier to
refine meshes (using the refine flags), as he or she has better
control over the above mentioned constraint. Or are in dealii

Thank You Bruno for the warning, I have never used it (I only assigned
boundary objects
to mesh). This feature is assumably more general

Good point -- see https://github.com/dealii/dealii/pull/2836

Is it possible to define a problem in spherical or cylindrical coordinate
system instead of Cartesian coordinate system?It would be very kind of you if
you refer me to a tutorial in which there is a problem that has been solved in
spherical or cylindrical coordinate system.
There is no such tu
Hello,
I have a vector valued (say, displacement) problem and I want to apply
Dirichlet boundary condition
corresponding to one component of the displacement vector to a single node
(whose position is know)
on a boundary.
I shall be thankful if someone can tell me how can I implement it in

Dear J-P,
Thanks for your response. I used the code for creating a quarter of a
circle that comes as follow:
Triangulation<2> triangulation;
const Point<2> center;
const double radius = 1.;
GridGenerator::half_hyper_ball(triangulation, center, radius);
Triangulation<2>::active_cell_iterator
