grad_grad: -Laplacian operator

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");
SEE ALSO
form(3), space(3) GRAD_GRAD(7)
