NAME¶

curl -- curl operator

SYNOPSIS¶

      form(const space V, const space& M, "curl");
 

DESCRIPTION¶

Assembly the form associated to the curl operator on finite element space. In three dimensions, both V and M are vector-valued:

               /
               |
      b(u,q) = |  curl(u).q dx
               |
               / Omega
 

In two dimensions, only V is vector-valued. The V space may be a either P2 finite element space, while the M space may be P1d. See also form(2) and space(2).

EXAMPLE¶

The following piece of code build the divergence form associated to the P2 approximation for a three dimensional geometry:

        geo omega("cube");
        space V(omega, "P2",  "vector");
        space M(omega, "P1d", "vector");
        form b(V, M, "curl");
 

while this code becomes in two dimension:

        geo omega("square");
        space V(omega, "P2",  "vector");
        space M(omega, "P1d");
        form b(V, M, "curl");
