Sharp and unified error estimates for the nonsymmetric Nitsche method on convex polytopes
Gang Chen, Chaoran Liu, Yangwen Zhang
Nitsche's method weakly imposes Dirichlet boundary conditions, but its nonsymmetric variant has long shown a gap between theory and computation: the classical ~analysis under…

An Incremental SVD Method for Non-Fickian Flows in Porous Media: Addressing Storage and Computational Challenges
Gang Chen, Yangwen Zhang, Dujin Zuo
It is well known that the numerical solution of the Non-Fickian flows at the current stage depends on all previous time instances. Consequently, the storage requirement increases l…
