First gravitational waves in FCF in a dynamical spacetime with matter content

Isabel Cordero-Carrión, Pablo Cerdá-Durán, José María Ibáñez

In this talk we present the recent work carried out to analyze numerically the behaviour of the hyperbolic sector of the Fully Constrained Formulation (FCF) (Bonazzola et al. 2004). The numerical experiments allow us to be confident in the performances of the upgraded version of CoCoNuT's code by replacing the Conformally Flat Condition (CFC), an approximation of Einstein equations, by FCF. First gravitational waves in FCF in a dynamical spacetime with matter content will be shown.
