Computational multiscale methods for quasi-gas dynamic equations

no code implementations31 Aug 2020 Boris Chetverushkin, Eric Chung, Yalchin Efendiev, Sai-Mang Pun, Zecheng Zhang

This multiscale problem is interesting from a multiscale methodology point of view as the model problem has a hyperbolic multiscale term, and designing multiscale methods for hyperbolic equations is challenging.
