Dear deal.ii community, I hope this message finds you well.
I am a student working on a project involving fourth-order PDEs (specifically, Kirchhoff plate problems), where C1-continuous finite elements are traditionally used. I understand that deal.ii does not have built-in C1 elements, and my project would benefit greatly from the *Hsieh-Clough-Tocher (HCT)* element. Therefore, I am writing to explore the feasibility of implementing the HCT element myself. My current understanding is that this would require creating a new class, `FE_HCT`, and defining its behavior in corresponding `fe_hct.h` and `fe_hct.cc` files, following the instructions in *The deal.II FAQ* : *“The actual implementation would most conveniently start from the `FE_Poly` class. You first implement the necessary polynomial space in the base library, then you derive `FE_Your_FE_Name` from `FE_Poly` (using your new polynomial class as a template) and add the connectivity information.”* I would greatly appreciate any high-level guidance on the implementation process, the potential challenges of developing such a complex composite element, and whether it is realistically feasible for an individual developer to accomplish this task. Thank you for your time and for maintaining this excellent library. Insights you can provide on the implementation path or feasibility analysis would be immensely helpful.
