6 Conclusions and Perspectives<br />

In this paper, we have presented an efficient method <strong>for</strong> obtaining anisotropic<br />

adapted meshes based on Riemannian metric specifications. This approach is<br />

based on amodification of the classical <strong>Delaunay</strong> kernel and involve local mesh<br />

modification operations. The results obtained so far in the numerical simulations<br />

are promising and confirm the cogency of the local modification strategy.<br />

The next stage will be to handle dynamically evolving domains where both the<br />

geometry and the topology of the domains change in time.<br />
