DESCRIPTION:Speakers: Emmanuel Franck (Inria Nancy Grand-est)\nIn this wor
k\, we are interested by the discretization of hyperbolic system with stif
f source term. Firstly we consider a simple linear case : the damped wave
equation which can be approximative by a diffusion equation at the limit.
For this equation we propose a asymptotic preserving scheme which converge
uniformly on general and unstructured 2D meshes contrary to the classical
extension of the AP which are not consistent in the limit regime on unstr
uctured meshes. After that we propose to extend this method to a nonlinear
problem: the Euler equations with friction. At the end the link with the
well-balanced scheme (for Euler-Poisson) will be introduced.\n\nhttps://in
