grad(3rheolef) rheolef-6.1 grad(3rheolef)
NAME
grad -- gradient operator
SYNOPSIS
form(const space V, const space& M, "grad");
DESCRIPTION
Assembly the form associated to the gradient operator on a finite element space V:
/
|
b(u, q) = | grad(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(2) and
space(2).
EXAMPLE
The following piece of code build the divergence form associated to the P1 approximation:
geo omega("square");
space V(omega, "P1");
space M(omega, "P0", "vector");
form b(V, M, "grad");
