Abstract:
A Finite-Volume/Finite-Element method developed in CFD is applied to solve numerically the time-dependent 2D Maxwell system. We use a third-order accurate explicit scheme with triangular meshes. We are particularly concerned here with scattering problems for both homogeneous and non-homogeneous materials. Radar Cross Section calculations are presented and compared with exact or integral method solutions. A parallel version of the algorithm on the Connection Machine is presented and the performances are compared with those obtained with a fully vectorized version on the CRAY YMP. Un solveur parallel de Maxwell instationnaire utilisant des sch'emas d'ecentr'es en maillages triangulaires R'esum'e: Une approximation mixte El'ements-finis/Volumes-finis d'evelopp'ee en m'ecanique des fluides est employ'ee ici pour la r'esolution num'erique des 'equations de Maxwell instationnaires en dimension deux d'espace. Nous utilisons un sch'ema explicite pr'ecis `a l'ordre trois avec des maillages triangulaires.
