Are C^1 Elements supported?

Question

Dears,

A simple question: What does "only partly supported." mean? in http://fenicsproject.org/documentation/dolfin/dev/python/programmers-reference/functions/functionspace/FunctionSpace.html

I want to use some C^1 element, but it seems that they are partially supported. I don't know what is the meaning of that. Does anyone know something about that? Is there an example with C^1 elements?

Thanks.

Answer 1

There are no C^1 elements implemented in FEniCS.
If you have a fourth order problem, the only way
you can implement it is through interior penalty methods
or mixed methods.

Thank you. I would like to solve the primal version of the weak form. But ok. I will split the equation and work in the mixed form.
