25 5 Conclusions The control-volume mixed nite element method provides a simple, systematic, easily implemented means of obtaining accurate, locally conservative velocities on irregular blockcentered grids, allowing for e ects of anisotropy and heterogeneity. Degrees of freedom consist of block pressures...

The mi-crostructure evolution problem is given a variational formulation in terms of incremental fields of displacement and order parameters, with unilateral constraints on volume fractions explicitly enforced by applying the augmented Lagrangian method. As an application, size-dependent microstructures with...
But the proof is parallel to that of Theorem 4.1, if we change the volume ?(X, (A + mL, hA hm )) of a subvariety V in X with respect to A + mL (see Lemma 4.1 L below) by the intersection number (A + mL)dim V · V . Example 2 To illustrate our method let us consider...
