NAME

       grad_grad -- -Laplacian operator

SYNOPSIS

             form(const space V, const space& V, "grad_grad");

DESCRIPTION

       Assembly  the  form  associated  to  the Laplacian operator on a finite
       element space V:

                      /
                      |
             a(u,v) = |  grad(u).grad(v) dx
                      |
                      / Omega

       The V space may be a either P1 , P2  or P1d  finite element space.  See
       also form(3) and space(3).

EXAMPLE

       The  following piece of code build the Laplacian form associated to the
       P1 approximation:

               geo g("square");
               space V(g, "P1");
               form a(V, V, "grad_grad");
