NAME

       div -- divergence operator

SYNOPSIS

             form(const space V, const space& M, "div");

DESCRIPTION

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

                      /
                      |
             b(u,q) = |  div(u) q dx
                      |
                      / Omega

       The  V space may be a either P1 or P2 finite element space, while the M space may be P0 or
       P1d respectively.  See also form(3) and space(3).

EXAMPLE

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

               geo omega("square");
               space V(omega, "P1", "vector");
               space M(omega, "P0");
               form b(V, M, "div");
