Does dell.II support comformal mesh adaption.

[ztdep...@gmail.com]

Dear sir:  

       I want to use the mesh adaptive capability of dell.II for my incompressible flow FVM computation.  I want to know that does dell.II suport conformal mesh adaption(do not have hanging node in the face).

Regards

that i snot possible. That being said, you really don't need to think to much about hanging nodes when using deal.II. 

The constraints are taken care off automatically when you do ConstraintMatrix::distributed_local_to_global()  for local vectors and matrices.

Correct. And to be specific, the *finite element spaces* we construct with the
constraints *are conforming*, even though the mesh may not be.
