Add to ORKGIn this report, we study two nodal discontinuous Galerkin (DG) methods, the centered flux DG method and the upwind flux DG method, for the resolution of the 2D elastic waves equations in frequency domain, so called Helmholtz equations. We give the formulation of both methods and we compare the obtained results.Dans ce rapport, nous étudions deux méthodes de Galerkine discontinues (GD), la méthode GD à flux centrés et la méthode GD à flux décentrés, pour la résolution des équations 2D des ondes élastiques en domaine fréquentiel, appelées aussi équations d’Helmholtz élastiques.Nous présentons la formulation des deux méthodes et nous comparons les résultats numériques obtenus
