Hi, I am a new deal.II user.
I'm solving a 2D problem on quadrilateral cartesian mesh using FE_Q(1) elements. I would like to compute the gradient of the bilinear solution, known to belong to the FE_Nedelec(0) space: how can I manage to do it? In particular I'm only interested in computing the tangential component of the gradient on each mesh face, but I don't really know (and can't find anything on the documentation) how to approach the problem of building a gradient vector associated with the Nédélec degrees of freedom. I've tried to loop over the active faces of the triangulation, but then I'm not able to detect the global dof index of each face (to be used for indexing the gradient vector). Any help is appreciated! Thanks in advance. -- The deal.II project is located at http://www.dealii.org/ For mailing list/forum options, see https://groups.google.com/d/forum/dealii?hl=en --- You received this message because you are subscribed to the Google Groups "deal.II User Group" group.
