Hello everyone, I recently finished my implementation of hanging nodes for the FE_NedelecSZ class with arbitrary polynomial degrees for the 2-D and 3-D cases. I will submit my implementation soon to deal.II on GitHub, but as the implementation was quite cumbersome and shall be part of my dissertation I want to publish my implementation along with a paper (or at least a preprint). At the moment that paper is my main priority, therefore It shouldn't take too long until I will publish my code.
In the meantime, I would suggest the same workaround as Alexander. Best, Sebastian Alexander schrieb am Montag, 24.
