摘要：
ATHENA2D is a finite element code dedicated to the wave propagation simulation. The good agreement between experimental and simulated data necessitates the use of accurate input data. Generally the input data are provided by experimental measurements and are consequently tainted with uncertainties. The aim of this study is to investigate the impact of these uncertainties on the numerical simulations using a probabilistic approach. This allows the determination of confidence intervals on ATHENA2D's output parameters.
