FEniCS finite element basis evaluation library

Basix is a finite element definition and tabulation runtime library.

Basix allows users to

  • evaluate finite element basis functions and their derivatives at a set of points
  • access geometric and topological information about reference cells
  • apply push forward and pull back operations to map data between a reference cell and a physical cell
  • permute and transform DOFs to allow higher-order elements to be use on arbitrary meshes
  • interpolate into a finite element space and between finite element spaces

Basix includes a range of built-in elements, and also allows the user to define their own custom elements.

Basix is one of the components of FEniCSx, alongside UFL, FFCx, and DOLFINx.
