This paper describes an automatic mesh generator suitable in general for nite element simulations. The mesh generator is of the Delaunay type and the paper focuses on recent improvements relative to this a priori well known method.
We introduce a new method to mesh a physical domain in parallel. Given a domain deened by a set of boundary facets, we construct a separator of it. As a result, we obtain several subdomains, each of them being deened by a set of boundary facets. Naturally, the separation step can be applied recursively to increase the number of subdomains, or to reduce the… (More)
SUMMARY This paper deals with adaptive simulation of time-dependent problems. Mesh adaptation for unsteady conÿgurations is especially important as the phenomenon evolves in the whole computational domain and, in order to capture such a phenomenon accurately on adapted meshes, one has to predict the evolution path. Here, we propose a new adaptive algorithm… (More)
Taking into account the drivers' state is a major challenge for designing new advanced driver assistance systems. In this paper we present a driver assistance system strongly coupled to the user. DAARIA<sup>1</sup> stands for Driver Assistance by Augmented Reality for Intelligent Automobile. It is an augmented reality interface powered by several sensors.… (More)

R ESUM E. Toute simulation par la m ethode des el ements nis de probl emes physiques mod-elis es en termes d' equations aux d eriv ees partielles n ecessite, dans une premi ere phase, la construction d'un maillage du domaine de calcul.

The journey which took place at Digital Domain called I, Robot all began with a very simple realization: This is the largest character based feature the studio has ever realized. This realization surfaced many concerns about our job structure and our toolset for such a large-scale character film. These new concerns raised ideas, and from these ideas were… (More)
