Deep Micro Solvers for Rough-Wall Stokes Flow in a Heterogeneous Multiscale Method
Emanuel Ström, Anna-Karin Tornberg, Ozan Ãktem
We propose a learned precomputation for the heterogeneous multiscale method (HMM) for rough-wall Stokes flow. A Fourier neural operator is used to approximate local averages over m…
