**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 spaceV: / | b(u,q) = | div(u) q dx | / Omega The V space may be a eitherP1orP2finite element space, while the M space may beP0orP1drespectively. See also form(3) and space(3).

**EXAMPLE**

The following piece of code build the divergence form associated to theP1approximation: geo omega("square"); space V(omega, "P1", "vector"); space M(omega, "P0"); form b(V, M, "div");
