Description
    Differential SGS Stress Equation Model
    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
    The DSEM uses a model version of the full balance equation for the SGS
    stress tensor to simulate the behaviour of B, hence,

        d/dt(B) + div(U*B) - div(nuSgs*grad(B))
        =
        P - c1*e/k*B - 0.667*(1 - c1)*e*I - c2*(P - 0.333*trP*I)

    where

        k = 0.5*trB,
        epsilon = ce*k^3/2/delta
        epsilon/k = ce*k^1/2/delta
        P = -(B'L + L'B)
        nuEff = ck*sqrt(k)*delta + nu

    This version from Launder, Rece & Rodi 1975
