I am currently using a FeSystem composed of two 3D Fields (real and
imaginary E-field) and I want to impose Dirichlet conditions of the sort
E(x,y,z) = E_{in}(x,y,z) on the input interface (in an xy-plane).
Earlier the z-component had been 0 so I did not run into real problems
and could use the project_boundary_values_curl_conforming_l2 function
(for the x and y components) and my own code for the z-components
(setting them 0 in the first cell layer). Now however I would like to
impose different values on the z-component. Since my cells have variable
thickness in z-direction (i.e. hanging node constraints appear) I would
like to use some library function for the interpolation.
Are there any feasible solutions to this?
Ideally I would like to keep using
project_boundary_values_curl_conforming_l2 for the tangential components
and just add some code for the z-components.
The question doesn't quite have enough information:
* Are you using Nedelec elements for the two fields?
* If the input face is in the xy-plane, and you are using a finite
element that is only curl-conforming (such as the Nedelec element),
isn't it correct that you can only prescribe *tangential* components for
boundary values? In other words, you cannot prescribe z-components anyway.
