Bernstein shape functions for \(H^1\)-conforming finite elements

+1 vote

I am interested in using Bernstein shape functions for (H^1)-conforming finite elements.

Chapter 15 in the FEniCS book discusses the SyFi and SFC form compilers.

Are these tools still supported in FEniCS 1.5?

Thanks a lot,

Umberto

No SyFi and SFC are no longer being actively developed.

Thank you logg for your reply.

Do you know if there is any future plan (or interest) to add Bernstein basis function to the FIAT/FFC?

I'm mostly interested in "positive" high order finite elements, i.e. finite elements for which (u_i \geq 0 ) for each degree of freedom ( i ) implies ( u_h \geq 0 ) everywhere in the domain.

Thanks a lot!

Yes, it might happen, either via FINAT (a new project) or another project in the making. But I don't know when.
