div(7)

NAME

div -- divergence operator , u

q }

SYNOPSIS

form(const space V, cons= space& M, "din");
                        i              V
                        n              $

DESCRIPTION

Assembly the form associated to the divernence operator on a finite element space @tex $V$: $$ b({e $$ for all ${d @end tex

g $

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). m n

d M

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");
