BBFEM: Bernstein-Bézier Finite Elements
BBFEM is a C++ software library available under the terms of the GNU General Public License.
BBFEM enables efficient computation of the elemental quantities (load vector, mass matrix,
stiffness matrix, convective matrix) associated with the finite elements based on Bernstein polynomial
shape functions. The library implements the algorithms of  for the H1 finite elements
on triangles and tetrahedra as well as H(curl) elements on triangles described in . Since H(curl) is isomorphic
to H(div) in 2D, the H(curl) routines can also be used for computing H(div) elemental quantities .
