Machine learning for accelerating macroscopic parameters prediction for poroelasticity problem in stochastic media
Autor: Maria V. Vasilyeva, Aleksey Tyrylgin
Publikováno v: Computers & Mathematics with Applications. 84:185-202
In this paper, we consider a coarse grid approximation (numerical homogenization and multiscale finite element method) for the poroelasticity problem with stochastic properties. The proposed method is based on the construction of deep neural network

Multiscale dimension reduction for flow and transport problems in thin domain with reactive boundaries
Autor: Maria V. Vasilyeva, Yalchin Efendiev, Valentin Alekseev, Eric T. Chung
In this paper, we consider flow and transport problems in thin domains. Modeling problems in thin domains occur in many applications, where thin domains lead to some type of reduced models. A typical example is one dimensional reduced-order model for
