grad_grad(3rheolef) rheolef-6.1 grad_grad(3rheolef)
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(2) and space(2).
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");
