Self-sustaining oscillations of a falling sphere through Johnson-Segalman fluids
Young-Ju Lee, Chen-Song Zhang
We confirm numerically that the Johnson-Segalman model is able to reproduce the continual oscillations of the falling sphere observed in some viscoelastic models. The empirical cho…
On Adaptive Eulerian-Lagrangian Method for Linear Convection-Diffusion Problems
Xiaozhe Hu, Young-Ju Lee, Jinchao Xu +1
In this paper, we consider the adaptive Eulerian--Lagrangian method (ELM) for linear convection-diffusion problems. Unlike the classical a posteriori error estimations, we estimate…
Axisymmetric Stokes equations in polygonal domains: regularity and finite element approximations
Young Ju Lee, Hengguang Li
We study the regularity and finite element approximation of the axisymmetric Stokes problem on a polygonal domain . In particular, taking into account the singular coefficients…
A Scalable Auxiliary Space Preconditioner for High-Order Finite Element Methods
Young-Ju Lee, Wei Leng, Chen-Song Zhang
In this paper, we revisit an auxiliary space preconditioning method proposed by Xu [Computing 56, 1996], in which low-order finite element spaces are employed as auxiliary spaces f…
