Anisotropy in Quadratic Simplex Elements

General
1

Hello :slight_smile:

I am new to FEniCS and am investigating whether I can switch from another FE package. I model the deformation of biological systems and reactions and am curious about FEniCS’ capabilities.

Is it possible in this package to define anisotropic material properties on quadratic simplex tetrahedral elements?

Thank you!

Yes, you can do this.

FEniCS uses the unified for language for specifying variational forms, that support anisotropic tensors:

and non-isoparametric elements, meaning you can have a simplex geometry with a quadratic Finite element space
