UFL input for P1 finite element
===============================

We define the finite element in UFL in a separate form file
:download:`P1.ufl`.  We define the linear finite element::

   element = FiniteElement("Lagrange", triangle, 1)

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 P1.ufl
