UFL input for P3 finite element
===============================

We define the finite element in UFL in a separate form file
:download:`P3.ufl`.  We define the linear finite element::

   element = FiniteElement("Lagrange", triangle, 3)

Before the form file can be used in the C++ program, it must be
compiled using FFC by running (on the command-line):

.. code-block:: sh

   ffc -l dolfin P3.ufl
