NAME¶

inv_mass -- invert of L2 scalar product

SYNOPSIS¶

        form(const space& V, const space& V, "inv_mass");
 

DESCRIPTION¶

Assembly the invert of the matrix associated to the L2 scalar product of the finite element space V:

                 /
                 |
        m(u,v) = | u v dx
                 |
                 / Omega
 

The V space may be either a P0 or P1d discontinuous finite element spaces see form(2).

EXAMPLE¶

The following piece of code build the invert of the mass matrix associated to the P1d approximation:

        geo omega_h ("square");
        space Vh (omega_h , "P1d");
        form im (Vh, Vh, "inv_mass");
