Uncertainty Quantification of Nonlinear Lagrangian Data Assimilation Using Linear Stochastic Forecast Models
Nan Chen, Shubin Fu
Lagrangian data assimilation exploits the trajectories of moving tracers as observations to recover the underlying flow field. One major challenge in Lagrangian data assimilation i…
A discontinuous Galerkin based multiscale method for heterogeneous elastic wave equations
Zhongqian Wang, Shubin Fu, Zishang Li +1
In this paper, we develop a local multiscale model reduction strategy for the elastic wave equation in strongly heterogeneous media, which is achieved by solving the problem in a c…
Local multiscale model reduction using discontinuous Galerkin coupling for elasticity problems
Zhongqian Wang, Shubin Fu, Eric Chung
In this paper, we consider the constrained energy minimizing generalized multiscale finite element method (CEM-GMsFEM) with discontinuous Galerkin (DG) coupling for the linear elas…
A conservative multiscale method for stochastic highly heterogeneous flow
Yiran Wang, Eric Chung, Shubin Fu
In this paper, we propose a local model reduction approach for subsurface flow problems in stochastic and highly heterogeneous media. To guarantee the mass conservation, we conside…
Generalized multiscale finite element method for highly heterogeneous compressible flow
Shubin Fu, Eric Chung, Lina Zhao
In this paper, we study the generalized multiscale finite element method (GMsFEM) for single phase compressible flow in highly heterogeneous porous media. We follow the major steps…
