La condensation de la matrice masse, ou mass-lumping, pour les éléments finis mixtes de Raviart–Thomas–Nédélec d'ordre 1

Abstract : Mass-lumping for the first order Raviart–Thomas–Nédélec finite elements. We present practical means to obtain a positive diagonal matrix for the first order Raviart–Thomas–Nédélec finite elements. Applying it to the second order Maxwell equations allows us to use explicit time schemes to solve the resulting differential system
