Learning adaptive coarse spaces of BDDC algorithms for stochastic elliptic problems with oscillatory and high contrast coefficients
Eric Chung, Hyea Hyun Kim, Ming Fai Lam +1
In this paper, we consider the balancing domain decomposition by constraints (BDDC) algorithm with adaptive coarse spaces for a class of stochastic elliptic problems. The key ingre…

A uniformly robust staggered DG method for the unsteady Darcy-Forchheimer-Brinkman problem
Lina Zhao, Ming Fai Lam, Eric Chung
In this paper we propose and analyze a uniformly robust staggered DG method for the unsteady Darcy-Forchheimer-Brinkman problem. Our formulation is based on velocity gradient-veloc…

A new staggered DG method for the Brinkman problem robust in the Darcy and Stokes limits
Lina Zhao, Eric Chung, Ming Fai Lam
In this paper we propose a novel staggered discontinuous Galerkin method for the Brinkman problem on general quadrilateral and polygonal meshes. The proposed method is robust in th…
